Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549972, here are decompositions:

  • 23 + 549949 = 549972
  • 29 + 549943 = 549972
  • 61 + 549911 = 549972
  • 89 + 549883 = 549972
  • 109 + 549863 = 549972
  • 139 + 549833 = 549972
  • 223 + 549749 = 549972
  • 233 + 549739 = 549972

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 549,972 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 549972 first appears in π at position 962,608 of the decimal expansion (the 962,608ordinal-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.
