Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85760, here are decompositions:

  • 43 + 85717 = 85760
  • 139 + 85621 = 85760
  • 163 + 85597 = 85760
  • 211 + 85549 = 85760
  • 229 + 85531 = 85760
  • 307 + 85453 = 85760
  • 313 + 85447 = 85760
  • 331 + 85429 = 85760

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85760 first appears in π at position 44,039 of the decimal expansion (the 44,039ordinal-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.
