Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78560, here are decompositions:

  • 7 + 78553 = 78560
  • 19 + 78541 = 78560
  • 43 + 78517 = 78560
  • 73 + 78487 = 78560
  • 193 + 78367 = 78560
  • 277 + 78283 = 78560
  • 283 + 78277 = 78560
  • 331 + 78229 = 78560

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 78560 first appears in π at position 67,485 of the decimal expansion (the 67,485ordinal-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.
