Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72202, here are decompositions:

  • 29 + 72173 = 72202
  • 41 + 72161 = 72202
  • 101 + 72101 = 72202
  • 113 + 72089 = 72202
  • 149 + 72053 = 72202
  • 239 + 71963 = 72202
  • 269 + 71933 = 72202
  • 293 + 71909 = 72202

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 72202 first appears in π at position 105,637 of the decimal expansion (the 105,637ordinal-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.
