Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985880, here are decompositions:

  • 3 + 985877 = 985880
  • 13 + 985867 = 985880
  • 61 + 985819 = 985880
  • 73 + 985807 = 985880
  • 97 + 985783 = 985880
  • 139 + 985741 = 985880
  • 151 + 985729 = 985880
  • 157 + 985723 = 985880

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 985,880 and was likely granted around 1910.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 985880 first appears in π at position 25,311 of the decimal expansion (the 25,311ordinal-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.
