Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28026, here are decompositions:

  • 7 + 28019 = 28026
  • 29 + 27997 = 28026
  • 43 + 27983 = 28026
  • 59 + 27967 = 28026
  • 73 + 27953 = 28026
  • 79 + 27947 = 28026
  • 83 + 27943 = 28026
  • 107 + 27919 = 28026

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28026 first appears in π at position 41,113 of the decimal expansion (the 41,113ordinal-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.
