Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147510278, here are decompositions:

  • 47 + 2147510231 = 2147510278
  • 131 + 2147510147 = 2147510278
  • 239 + 2147510039 = 2147510278
  • 281 + 2147509997 = 2147510278
  • 461 + 2147509817 = 2147510278
  • 479 + 2147509799 = 2147510278
  • 491 + 2147509787 = 2147510278
  • 647 + 2147509631 = 2147510278

Showing the first eight; more decompositions exist.
