Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77684, here are decompositions:

  • 3 + 77681 = 77684
  • 37 + 77647 = 77684
  • 43 + 77641 = 77684
  • 67 + 77617 = 77684
  • 73 + 77611 = 77684
  • 97 + 77587 = 77684
  • 127 + 77557 = 77684
  • 157 + 77527 = 77684

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77684 first appears in π at position 47,201 of the decimal expansion (the 47,201ordinal-suffix:st 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.
