Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147498394, here are decompositions:

  • 7 + 2147498387 = 2147498394
  • 31 + 2147498363 = 2147498394
  • 47 + 2147498347 = 2147498394
  • 53 + 2147498341 = 2147498394
  • 61 + 2147498333 = 2147498394
  • 277 + 2147498117 = 2147498394
  • 317 + 2147498077 = 2147498394
  • 487 + 2147497907 = 2147498394

Showing the first eight; more decompositions exist.
