Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85880, here are decompositions:

  • 37 + 85843 = 85880
  • 43 + 85837 = 85880
  • 61 + 85819 = 85880
  • 163 + 85717 = 85880
  • 211 + 85669 = 85880
  • 241 + 85639 = 85880
  • 283 + 85597 = 85880
  • 331 + 85549 = 85880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85880 first appears in π at position 25,312 of the decimal expansion (the 25,312ordinal-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.
