Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534494, here are decompositions:

  • 7 + 31534487 = 31534494
  • 11 + 31534483 = 31534494
  • 37 + 31534457 = 31534494
  • 53 + 31534441 = 31534494
  • 67 + 31534427 = 31534494
  • 71 + 31534423 = 31534494
  • 83 + 31534411 = 31534494
  • 151 + 31534343 = 31534494

Showing the first eight; more decompositions exist.
