Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28056, here are decompositions:

  • 5 + 28051 = 28056
  • 29 + 28027 = 28056
  • 37 + 28019 = 28056
  • 59 + 27997 = 28056
  • 73 + 27983 = 28056
  • 89 + 27967 = 28056
  • 103 + 27953 = 28056
  • 109 + 27947 = 28056

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28056 first appears in π at position 56,889 of the decimal expansion (the 56,889ordinal-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.
