Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399342, here are decompositions:

  • 13 + 2147399329 = 2147399342
  • 79 + 2147399263 = 2147399342
  • 139 + 2147399203 = 2147399342
  • 181 + 2147399161 = 2147399342
  • 229 + 2147399113 = 2147399342
  • 373 + 2147398969 = 2147399342
  • 379 + 2147398963 = 2147399342
  • 523 + 2147398819 = 2147399342

Showing the first eight; more decompositions exist.
