Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26838, here are decompositions:

  • 5 + 26833 = 26838
  • 17 + 26821 = 26838
  • 37 + 26801 = 26838
  • 61 + 26777 = 26838
  • 79 + 26759 = 26838
  • 101 + 26737 = 26838
  • 107 + 26731 = 26838
  • 109 + 26729 = 26838

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26838 first appears in π at position 273,761 of the decimal expansion (the 273,761ordinal-suffix:st 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.
