Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499618, here are decompositions:

  • 41 + 2147499577 = 2147499618
  • 71 + 2147499547 = 2147499618
  • 79 + 2147499539 = 2147499618
  • 97 + 2147499521 = 2147499618
  • 107 + 2147499511 = 2147499618
  • 109 + 2147499509 = 2147499618
  • 137 + 2147499481 = 2147499618
  • 139 + 2147499479 = 2147499618

Showing the first eight; more decompositions exist.
