Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61320, here are decompositions:

  • 23 + 61297 = 61320
  • 29 + 61291 = 61320
  • 37 + 61283 = 61320
  • 59 + 61261 = 61320
  • 67 + 61253 = 61320
  • 89 + 61231 = 61320
  • 97 + 61223 = 61320
  • 109 + 61211 = 61320

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 61320 first appears in π at position 126,996 of the decimal expansion (the 126,996ordinal-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.
