Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 471808, here are decompositions:

  • 5 + 471803 = 471808
  • 17 + 471791 = 471808
  • 59 + 471749 = 471808
  • 89 + 471719 = 471808
  • 131 + 471677 = 471808
  • 137 + 471671 = 471808
  • 149 + 471659 = 471808
  • 167 + 471641 = 471808

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 471,808 and was likely granted around 1891.

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

Position in π

The digit sequence 471808 first appears in π at position 219,996 of the decimal expansion (the 219,996ordinal-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.
