Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525492, here are decompositions:

  • 3 + 31525489 = 31525492
  • 71 + 31525421 = 31525492
  • 113 + 31525379 = 31525492
  • 149 + 31525343 = 31525492
  • 263 + 31525229 = 31525492
  • 281 + 31525211 = 31525492
  • 389 + 31525103 = 31525492
  • 461 + 31525031 = 31525492

Showing the first eight; more decompositions exist.
