Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 949870, here are decompositions:

  • 17 + 949853 = 949870
  • 59 + 949811 = 949870
  • 137 + 949733 = 949870
  • 179 + 949691 = 949870
  • 197 + 949673 = 949870
  • 227 + 949643 = 949870
  • 239 + 949631 = 949870
  • 263 + 949607 = 949870

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 949,870 and was likely granted around 1909.

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

Position in π

The digit sequence 949870 first appears in π at position 613,619 of the decimal expansion (the 613,619ordinal-suffix:th 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.
