Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 985580, here are decompositions:

  • 61 + 985519 = 985580
  • 97 + 985483 = 985580
  • 109 + 985471 = 985580
  • 163 + 985417 = 985580
  • 181 + 985399 = 985580
  • 229 + 985351 = 985580
  • 241 + 985339 = 985580
  • 367 + 985213 = 985580

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 985,580 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 985580 first appears in π at position 501,633 of the decimal expansion (the 501,633ordinal-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.
