Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77784, here are decompositions:

  • 11 + 77773 = 77784
  • 23 + 77761 = 77784
  • 37 + 77747 = 77784
  • 41 + 77743 = 77784
  • 53 + 77731 = 77784
  • 61 + 77723 = 77784
  • 71 + 77713 = 77784
  • 73 + 77711 = 77784

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77784 first appears in π at position 69,842 of the decimal expansion (the 69,842ordinal-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.
