Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27992, here are decompositions:

  • 31 + 27961 = 27992
  • 73 + 27919 = 27992
  • 109 + 27883 = 27992
  • 193 + 27799 = 27992
  • 199 + 27793 = 27992
  • 229 + 27763 = 27992
  • 241 + 27751 = 27992
  • 409 + 27583 = 27992

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27992 first appears in π at position 14,994 of the decimal expansion (the 14,994ordinal-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.
