Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422090, here are decompositions:

  • 3 + 2147422087 = 2147422090
  • 29 + 2147422061 = 2147422090
  • 53 + 2147422037 = 2147422090
  • 71 + 2147422019 = 2147422090
  • 101 + 2147421989 = 2147422090
  • 137 + 2147421953 = 2147422090
  • 179 + 2147421911 = 2147422090
  • 197 + 2147421893 = 2147422090

Showing the first eight; more decompositions exist.
