Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498218, here are decompositions:

  • 29 + 2147498189 = 2147498218
  • 71 + 2147498147 = 2147498218
  • 101 + 2147498117 = 2147498218
  • 269 + 2147497949 = 2147498218
  • 311 + 2147497907 = 2147498218
  • 317 + 2147497901 = 2147498218
  • 449 + 2147497769 = 2147498218
  • 461 + 2147497757 = 2147498218

Showing the first eight; more decompositions exist.
