Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 549720, here are decompositions:

  • 7 + 549713 = 549720
  • 13 + 549707 = 549720
  • 19 + 549701 = 549720
  • 29 + 549691 = 549720
  • 37 + 549683 = 549720
  • 53 + 549667 = 549720
  • 71 + 549649 = 549720
  • 79 + 549641 = 549720

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 549,720 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 549720 first appears in π at position 383,921 of the decimal expansion (the 383,921ordinal-suffix:st 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.
