Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497822, here are decompositions:

  • 53 + 2147497769 = 2147497822
  • 89 + 2147497733 = 2147497822
  • 131 + 2147497691 = 2147497822
  • 251 + 2147497571 = 2147497822
  • 263 + 2147497559 = 2147497822
  • 419 + 2147497403 = 2147497822
  • 461 + 2147497361 = 2147497822
  • 881 + 2147496941 = 2147497822

Showing the first eight; more decompositions exist.
