Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498490, here are decompositions:

  • 19 + 2147498471 = 2147498490
  • 41 + 2147498449 = 2147498490
  • 97 + 2147498393 = 2147498490
  • 103 + 2147498387 = 2147498490
  • 127 + 2147498363 = 2147498490
  • 149 + 2147498341 = 2147498490
  • 157 + 2147498333 = 2147498490
  • 211 + 2147498279 = 2147498490

Showing the first eight; more decompositions exist.
