Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530868, here are decompositions:

  • 41 + 31530827 = 31530868
  • 71 + 31530797 = 31530868
  • 167 + 31530701 = 31530868
  • 227 + 31530641 = 31530868
  • 251 + 31530617 = 31530868
  • 389 + 31530479 = 31530868
  • 431 + 31530437 = 31530868
  • 449 + 31530419 = 31530868

Showing the first eight; more decompositions exist.
