Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147374512, here are decompositions:

  • 53 + 2147374459 = 2147374512
  • 181 + 2147374331 = 2147374512
  • 211 + 2147374301 = 2147374512
  • 229 + 2147374283 = 2147374512
  • 233 + 2147374279 = 2147374512
  • 271 + 2147374241 = 2147374512
  • 379 + 2147374133 = 2147374512
  • 461 + 2147374051 = 2147374512

Showing the first eight; more decompositions exist.
