Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537604, here are decompositions:

  • 13 + 31537591 = 31537604
  • 31 + 31537573 = 31537604
  • 61 + 31537543 = 31537604
  • 97 + 31537507 = 31537604
  • 127 + 31537477 = 31537604
  • 277 + 31537327 = 31537604
  • 331 + 31537273 = 31537604
  • 337 + 31537267 = 31537604

Showing the first eight; more decompositions exist.
