Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147388452, here are decompositions:

  • 43 + 2147388409 = 2147388452
  • 151 + 2147388301 = 2147388452
  • 199 + 2147388253 = 2147388452
  • 211 + 2147388241 = 2147388452
  • 241 + 2147388211 = 2147388452
  • 409 + 2147388043 = 2147388452
  • 613 + 2147387839 = 2147388452
  • 631 + 2147387821 = 2147388452

Showing the first eight; more decompositions exist.
