Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 481216, here are decompositions:

  • 5 + 481211 = 481216
  • 17 + 481199 = 481216
  • 59 + 481157 = 481216
  • 83 + 481133 = 481216
  • 107 + 481109 = 481216
  • 149 + 481067 = 481216
  • 173 + 481043 = 481216
  • 227 + 480989 = 481216

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 481,216 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 481216 first appears in π at position 980,632 of the decimal expansion (the 980,632ordinal-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.
