Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28162, here are decompositions:

  • 11 + 28151 = 28162
  • 53 + 28109 = 28162
  • 131 + 28031 = 28162
  • 179 + 27983 = 28162
  • 269 + 27893 = 28162
  • 311 + 27851 = 28162
  • 353 + 27809 = 28162
  • 359 + 27803 = 28162

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 28162 first appears in π at position 8,394 of the decimal expansion (the 8,394ordinal-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.
