Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147538540, here are decompositions:

  • 13 + 2147538527 = 2147538540
  • 19 + 2147538521 = 2147538540
  • 31 + 2147538509 = 2147538540
  • 47 + 2147538493 = 2147538540
  • 79 + 2147538461 = 2147538540
  • 101 + 2147538439 = 2147538540
  • 107 + 2147538433 = 2147538540
  • 139 + 2147538401 = 2147538540

Showing the first eight; more decompositions exist.
