Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76880, here are decompositions:

  • 7 + 76873 = 76880
  • 43 + 76837 = 76880
  • 61 + 76819 = 76880
  • 79 + 76801 = 76880
  • 103 + 76777 = 76880
  • 109 + 76771 = 76880
  • 127 + 76753 = 76880
  • 163 + 76717 = 76880

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 76880 first appears in π at position 271,823 of the decimal expansion (the 271,823ordinal-suffix:rd 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.
