Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009810, here are decompositions:

  • 3 + 1009807 = 1009810
  • 23 + 1009787 = 1009810
  • 29 + 1009781 = 1009810
  • 83 + 1009727 = 1009810
  • 167 + 1009643 = 1009810
  • 173 + 1009637 = 1009810
  • 251 + 1009559 = 1009810
  • 311 + 1009499 = 1009810

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,009,810 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1009810 first appears in π at position 367,681 of the decimal expansion (the 367,681ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
