Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549812, here are decompositions:

  • 61 + 549751 = 549812
  • 73 + 549739 = 549812
  • 79 + 549733 = 549812
  • 163 + 549649 = 549812
  • 223 + 549589 = 549812
  • 331 + 549481 = 549812
  • 409 + 549403 = 549812
  • 421 + 549391 = 549812

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 549,812 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 549812 first appears in π at position 381,084 of the decimal expansion (the 381,084ordinal-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.
