Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7758, here are decompositions:

  • 5 + 7753 = 7758
  • 17 + 7741 = 7758
  • 31 + 7727 = 7758
  • 41 + 7717 = 7758
  • 59 + 7699 = 7758
  • 67 + 7691 = 7758
  • 71 + 7687 = 7758
  • 89 + 7669 = 7758

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7758 first appears in π at position 12,662 of the decimal expansion (the 12,662ordinal-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.
