Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980900, here are decompositions:

  • 3 + 980897 = 980900
  • 7 + 980893 = 980900
  • 13 + 980887 = 980900
  • 73 + 980827 = 980900
  • 97 + 980803 = 980900
  • 127 + 980773 = 980900
  • 181 + 980719 = 980900
  • 211 + 980689 = 980900

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 980,900 and was likely granted around 1910.

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

Position in π

The digit sequence 980900 first appears in π at position 164,192 of the decimal expansion (the 164,192ordinal-suffix:nd 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.
