Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 469220, here are decompositions:

  • 13 + 469207 = 469220
  • 67 + 469153 = 469220
  • 79 + 469141 = 469220
  • 151 + 469069 = 469220
  • 211 + 469009 = 469220
  • 307 + 468913 = 469220
  • 331 + 468889 = 469220
  • 337 + 468883 = 469220

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 469,220 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 469220 first appears in π at position 611,705 of the decimal expansion (the 611,705ordinal-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.
