Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77722, here are decompositions:

  • 3 + 77719 = 77722
  • 11 + 77711 = 77722
  • 23 + 77699 = 77722
  • 41 + 77681 = 77722
  • 101 + 77621 = 77722
  • 131 + 77591 = 77722
  • 149 + 77573 = 77722
  • 173 + 77549 = 77722

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77722 first appears in π at position 19,903 of the decimal expansion (the 19,903ordinal-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.
