Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549810, here are decompositions:

  • 43 + 549767 = 549810
  • 59 + 549751 = 549810
  • 61 + 549749 = 549810
  • 71 + 549739 = 549810
  • 73 + 549737 = 549810
  • 97 + 549713 = 549810
  • 103 + 549707 = 549810
  • 109 + 549701 = 549810

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 549,810 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 549810 first appears in π at position 685,273 of the decimal expansion (the 685,273ordinal-suffix:rd 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.
