Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492990, here are decompositions:

  • 31 + 2147492959 = 2147492990
  • 61 + 2147492929 = 2147492990
  • 67 + 2147492923 = 2147492990
  • 337 + 2147492653 = 2147492990
  • 439 + 2147492551 = 2147492990
  • 457 + 2147492533 = 2147492990
  • 463 + 2147492527 = 2147492990
  • 499 + 2147492491 = 2147492990

Showing the first eight; more decompositions exist.
