Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473518, here are decompositions:

  • 31 + 2147473487 = 2147473518
  • 41 + 2147473477 = 2147473518
  • 89 + 2147473429 = 2147473518
  • 109 + 2147473409 = 2147473518
  • 149 + 2147473369 = 2147473518
  • 167 + 2147473351 = 2147473518
  • 227 + 2147473291 = 2147473518
  • 251 + 2147473267 = 2147473518

Showing the first eight; more decompositions exist.
