Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28774, here are decompositions:

  • 3 + 28771 = 28774
  • 23 + 28751 = 28774
  • 71 + 28703 = 28774
  • 113 + 28661 = 28774
  • 131 + 28643 = 28774
  • 167 + 28607 = 28774
  • 227 + 28547 = 28774
  • 233 + 28541 = 28774

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28774 first appears in π at position 328,917 of the decimal expansion (the 328,917ordinal-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.
