Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77650, here are decompositions:

  • 3 + 77647 = 77650
  • 29 + 77621 = 77650
  • 59 + 77591 = 77650
  • 101 + 77549 = 77650
  • 107 + 77543 = 77650
  • 137 + 77513 = 77650
  • 173 + 77477 = 77650
  • 179 + 77471 = 77650

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 77650 first appears in π at position 21,424 of the decimal expansion (the 21,424ordinal-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.
