Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20326, here are decompositions:

  • 3 + 20323 = 20326
  • 29 + 20297 = 20326
  • 107 + 20219 = 20326
  • 149 + 20177 = 20326
  • 179 + 20147 = 20326
  • 197 + 20129 = 20326
  • 263 + 20063 = 20326
  • 347 + 19979 = 20326

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20326 first appears in π at position 131,986 of the decimal expansion (the 131,986ordinal-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.
