Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147501218, here are decompositions:

  • 41 + 2147501177 = 2147501218
  • 89 + 2147501129 = 2147501218
  • 281 + 2147500937 = 2147501218
  • 311 + 2147500907 = 2147501218
  • 347 + 2147500871 = 2147501218
  • 521 + 2147500697 = 2147501218
  • 557 + 2147500661 = 2147501218
  • 659 + 2147500559 = 2147501218

Showing the first eight; more decompositions exist.
