Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28834, here are decompositions:

  • 17 + 28817 = 28834
  • 41 + 28793 = 28834
  • 83 + 28751 = 28834
  • 131 + 28703 = 28834
  • 137 + 28697 = 28834
  • 173 + 28661 = 28834
  • 191 + 28643 = 28834
  • 227 + 28607 = 28834

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28834 first appears in π at position 74,448 of the decimal expansion (the 74,448ordinal-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.
