Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27798, here are decompositions:

  • 5 + 27793 = 27798
  • 7 + 27791 = 27798
  • 19 + 27779 = 27798
  • 31 + 27767 = 27798
  • 47 + 27751 = 27798
  • 59 + 27739 = 27798
  • 61 + 27737 = 27798
  • 97 + 27701 = 27798

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27798 first appears in π at position 610,129 of the decimal expansion (the 610,129ordinal-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.
