Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13426, here are decompositions:

  • 5 + 13421 = 13426
  • 29 + 13397 = 13426
  • 59 + 13367 = 13426
  • 89 + 13337 = 13426
  • 113 + 13313 = 13426
  • 167 + 13259 = 13426
  • 197 + 13229 = 13426
  • 239 + 13187 = 13426

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 13426 first appears in π at position 119,313 of the decimal expansion (the 119,313ordinal-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.
