Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488290, here are decompositions:

  • 11 + 2147488279 = 2147488290
  • 41 + 2147488249 = 2147488290
  • 43 + 2147488247 = 2147488290
  • 127 + 2147488163 = 2147488290
  • 137 + 2147488153 = 2147488290
  • 139 + 2147488151 = 2147488290
  • 179 + 2147488111 = 2147488290
  • 223 + 2147488067 = 2147488290

Showing the first eight; more decompositions exist.
