Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147500680, here are decompositions:

  • 19 + 2147500661 = 2147500680
  • 53 + 2147500627 = 2147500680
  • 67 + 2147500613 = 2147500680
  • 89 + 2147500591 = 2147500680
  • 173 + 2147500507 = 2147500680
  • 181 + 2147500499 = 2147500680
  • 337 + 2147500343 = 2147500680
  • 379 + 2147500301 = 2147500680

Showing the first eight; more decompositions exist.
