Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77600, here are decompositions:

  • 13 + 77587 = 77600
  • 31 + 77569 = 77600
  • 37 + 77563 = 77600
  • 43 + 77557 = 77600
  • 73 + 77527 = 77600
  • 79 + 77521 = 77600
  • 109 + 77491 = 77600
  • 181 + 77419 = 77600

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77600 first appears in π at position 318,042 of the decimal expansion (the 318,042ordinal-suffix:nd 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.
