Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28292, here are decompositions:

  • 3 + 28289 = 28292
  • 13 + 28279 = 28292
  • 73 + 28219 = 28292
  • 109 + 28183 = 28292
  • 181 + 28111 = 28292
  • 193 + 28099 = 28292
  • 211 + 28081 = 28292
  • 223 + 28069 = 28292

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28292 first appears in π at position 333 of the decimal expansion (the 333ordinal-suffix:rd 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.
