Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525616, here are decompositions:

  • 7 + 31525609 = 31525616
  • 13 + 31525603 = 31525616
  • 79 + 31525537 = 31525616
  • 127 + 31525489 = 31525616
  • 139 + 31525477 = 31525616
  • 337 + 31525279 = 31525616
  • 349 + 31525267 = 31525616
  • 373 + 31525243 = 31525616

Showing the first eight; more decompositions exist.
