Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147573678, here are decompositions:

  • 67 + 2147573611 = 2147573678
  • 79 + 2147573599 = 2147573678
  • 127 + 2147573551 = 2147573678
  • 139 + 2147573539 = 2147573678
  • 181 + 2147573497 = 2147573678
  • 241 + 2147573437 = 2147573678
  • 337 + 2147573341 = 2147573678
  • 379 + 2147573299 = 2147573678

Showing the first eight; more decompositions exist.
