Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485728, here are decompositions:

  • 11 + 485717 = 485728
  • 71 + 485657 = 485728
  • 281 + 485447 = 485728
  • 311 + 485417 = 485728
  • 317 + 485411 = 485728
  • 521 + 485207 = 485728
  • 557 + 485171 = 485728
  • 647 + 485081 = 485728

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 485,728 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 485728 first appears in π at position 426,701 of the decimal expansion (the 426,701ordinal-suffix:st 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.
