Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481812, here are decompositions:

  • 5 + 481807 = 481812
  • 11 + 481801 = 481812
  • 43 + 481769 = 481812
  • 59 + 481753 = 481812
  • 61 + 481751 = 481812
  • 113 + 481699 = 481812
  • 131 + 481681 = 481812
  • 139 + 481673 = 481812

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 481,812 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 481812 first appears in π at position 580,699 of the decimal expansion (the 580,699ordinal-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.
