Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469854, here are decompositions:

  • 31 + 2147469823 = 2147469854
  • 37 + 2147469817 = 2147469854
  • 73 + 2147469781 = 2147469854
  • 151 + 2147469703 = 2147469854
  • 433 + 2147469421 = 2147469854
  • 571 + 2147469283 = 2147469854
  • 787 + 2147469067 = 2147469854
  • 853 + 2147469001 = 2147469854

Showing the first eight; more decompositions exist.
