Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500812, here are decompositions:

  • 31 + 2147500781 = 2147500812
  • 89 + 2147500723 = 2147500812
  • 151 + 2147500661 = 2147500812
  • 199 + 2147500613 = 2147500812
  • 251 + 2147500561 = 2147500812
  • 313 + 2147500499 = 2147500812
  • 461 + 2147500351 = 2147500812
  • 571 + 2147500241 = 2147500812

Showing the first eight; more decompositions exist.
