Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978560, here are decompositions:

  • 19 + 978541 = 978560
  • 97 + 978463 = 978560
  • 103 + 978457 = 978560
  • 157 + 978403 = 978560
  • 211 + 978349 = 978560
  • 223 + 978337 = 978560
  • 277 + 978283 = 978560
  • 283 + 978277 = 978560

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 978,560 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 978560 first appears in π at position 527,641 of the decimal expansion (the 527,641ordinal-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.
