Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7776, here are decompositions:

  • 17 + 7759 = 7776
  • 19 + 7757 = 7776
  • 23 + 7753 = 7776
  • 53 + 7723 = 7776
  • 59 + 7717 = 7776
  • 73 + 7703 = 7776
  • 89 + 7687 = 7776
  • 103 + 7673 = 7776

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 7776 first appears in π at position 11,298 of the decimal expansion (the 11,298ordinal-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.
