Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31580848, here are decompositions:

  • 41 + 31580807 = 31580848
  • 59 + 31580789 = 31580848
  • 107 + 31580741 = 31580848
  • 137 + 31580711 = 31580848
  • 179 + 31580669 = 31580848
  • 227 + 31580621 = 31580848
  • 317 + 31580531 = 31580848
  • 347 + 31580501 = 31580848

Showing the first eight; more decompositions exist.
