Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147377492, here are decompositions:

  • 3 + 2147377489 = 2147377492
  • 5 + 2147377487 = 2147377492
  • 11 + 2147377481 = 2147377492
  • 23 + 2147377469 = 2147377492
  • 149 + 2147377343 = 2147377492
  • 251 + 2147377241 = 2147377492
  • 503 + 2147376989 = 2147377492
  • 509 + 2147376983 = 2147377492

Showing the first eight; more decompositions exist.
