Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 475820, here are decompositions:

  • 13 + 475807 = 475820
  • 31 + 475789 = 475820
  • 43 + 475777 = 475820
  • 61 + 475759 = 475820
  • 67 + 475753 = 475820
  • 127 + 475693 = 475820
  • 139 + 475681 = 475820
  • 151 + 475669 = 475820

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 475,820 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 475820 first appears in π at position 659,211 of the decimal expansion (the 659,211ordinal-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.
