Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 26400, here are decompositions:

  • 7 + 26393 = 26400
  • 13 + 26387 = 26400
  • 29 + 26371 = 26400
  • 43 + 26357 = 26400
  • 53 + 26347 = 26400
  • 61 + 26339 = 26400
  • 79 + 26321 = 26400
  • 83 + 26317 = 26400

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 26400 first appears in π at position 12,271 of the decimal expansion (the 12,271ordinal-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.
