Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500618, here are decompositions:

  • 5 + 2147500613 = 2147500618
  • 59 + 2147500559 = 2147500618
  • 257 + 2147500361 = 2147500618
  • 317 + 2147500301 = 2147500618
  • 359 + 2147500259 = 2147500618
  • 479 + 2147500139 = 2147500618
  • 491 + 2147500127 = 2147500618
  • 569 + 2147500049 = 2147500618

Showing the first eight; more decompositions exist.
