Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147581084, here are decompositions:

  • 3 + 2147581081 = 2147581084
  • 41 + 2147581043 = 2147581084
  • 71 + 2147581013 = 2147581084
  • 107 + 2147580977 = 2147581084
  • 251 + 2147580833 = 2147581084
  • 263 + 2147580821 = 2147581084
  • 461 + 2147580623 = 2147581084
  • 491 + 2147580593 = 2147581084

Showing the first eight; more decompositions exist.
