Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 485780, here are decompositions:

  • 3 + 485777 = 485780
  • 79 + 485701 = 485780
  • 109 + 485671 = 485780
  • 193 + 485587 = 485780
  • 271 + 485509 = 485780
  • 283 + 485497 = 485780
  • 397 + 485383 = 485780
  • 409 + 485371 = 485780

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 485,780 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 485780 first appears in π at position 968,193 of the decimal expansion (the 968,193ordinal-suffix:rd 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.
