Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31531036, here are decompositions:

  • 59 + 31530977 = 31531036
  • 239 + 31530797 = 31531036
  • 263 + 31530773 = 31531036
  • 353 + 31530683 = 31531036
  • 419 + 31530617 = 31531036
  • 443 + 31530593 = 31531036
  • 557 + 31530479 = 31531036
  • 599 + 31530437 = 31531036

Showing the first eight; more decompositions exist.
