Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472220, here are decompositions:

  • 31 + 472189 = 472220
  • 61 + 472159 = 472220
  • 97 + 472123 = 472220
  • 109 + 472111 = 472220
  • 157 + 472063 = 472220
  • 163 + 472057 = 472220
  • 193 + 472027 = 472220
  • 223 + 471997 = 472220

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 472,220 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 472220 first appears in π at position 311,292 of the decimal expansion (the 311,292ordinal-suffix:nd 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.
