Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549742, here are decompositions:

  • 3 + 549739 = 549742
  • 5 + 549737 = 549742
  • 23 + 549719 = 549742
  • 29 + 549713 = 549742
  • 41 + 549701 = 549742
  • 59 + 549683 = 549742
  • 101 + 549641 = 549742
  • 173 + 549569 = 549742

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 549,742 and was likely granted around 1895.

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

Position in π

The digit sequence 549742 first appears in π at position 644,990 of the decimal expansion (the 644,990ordinal-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.
