Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549042, here are decompositions:

  • 5 + 549037 = 549042
  • 19 + 549023 = 549042
  • 23 + 549019 = 549042
  • 29 + 549013 = 549042
  • 31 + 549011 = 549042
  • 41 + 549001 = 549042
  • 79 + 548963 = 549042
  • 89 + 548953 = 549042

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 549,042 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 549042 first appears in π at position 907,173 of the decimal expansion (the 907,173ordinal-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.
