Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 82784, here are decompositions:

  • 3 + 82781 = 82784
  • 61 + 82723 = 82784
  • 127 + 82657 = 82784
  • 151 + 82633 = 82784
  • 193 + 82591 = 82784
  • 223 + 82561 = 82784
  • 277 + 82507 = 82784
  • 313 + 82471 = 82784

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 82784 first appears in π at position 250,274 of the decimal expansion (the 250,274ordinal-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.
