Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549800, here are decompositions:

  • 61 + 549739 = 549800
  • 67 + 549733 = 549800
  • 109 + 549691 = 549800
  • 151 + 549649 = 549800
  • 157 + 549643 = 549800
  • 193 + 549607 = 549800
  • 211 + 549589 = 549800
  • 283 + 549517 = 549800

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 549,800 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 549800 first appears in π at position 74,210 of the decimal expansion (the 74,210ordinal-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.
