Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493540, here are decompositions:

  • 61 + 2147493479 = 2147493540
  • 83 + 2147493457 = 2147493540
  • 107 + 2147493433 = 2147493540
  • 131 + 2147493409 = 2147493540
  • 149 + 2147493391 = 2147493540
  • 229 + 2147493311 = 2147493540
  • 239 + 2147493301 = 2147493540
  • 251 + 2147493289 = 2147493540

Showing the first eight; more decompositions exist.
