Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27996, here are decompositions:

  • 13 + 27983 = 27996
  • 29 + 27967 = 27996
  • 43 + 27953 = 27996
  • 53 + 27943 = 27996
  • 79 + 27917 = 27996
  • 103 + 27893 = 27996
  • 113 + 27883 = 27996
  • 149 + 27847 = 27996

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 27996 first appears in π at position 50,237 of the decimal expansion (the 50,237ordinal-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.
