Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147581112, here are decompositions:

  • 31 + 2147581081 = 2147581112
  • 43 + 2147581069 = 2147581112
  • 331 + 2147580781 = 2147581112
  • 379 + 2147580733 = 2147581112
  • 499 + 2147580613 = 2147581112
  • 613 + 2147580499 = 2147581112
  • 673 + 2147580439 = 2147581112
  • 739 + 2147580373 = 2147581112

Showing the first eight; more decompositions exist.
