Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498470, here are decompositions:

  • 71 + 2147498399 = 2147498470
  • 83 + 2147498387 = 2147498470
  • 107 + 2147498363 = 2147498470
  • 137 + 2147498333 = 2147498470
  • 191 + 2147498279 = 2147498470
  • 281 + 2147498189 = 2147498470
  • 353 + 2147498117 = 2147498470
  • 521 + 2147497949 = 2147498470

Showing the first eight; more decompositions exist.
