Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493342, here are decompositions:

  • 31 + 2147493311 = 2147493342
  • 41 + 2147493301 = 2147493342
  • 53 + 2147493289 = 2147493342
  • 61 + 2147493281 = 2147493342
  • 101 + 2147493241 = 2147493342
  • 173 + 2147493169 = 2147493342
  • 223 + 2147493119 = 2147493342
  • 233 + 2147493109 = 2147493342

Showing the first eight; more decompositions exist.
