Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375830, here are decompositions:

  • 23 + 2147375807 = 2147375830
  • 101 + 2147375729 = 2147375830
  • 137 + 2147375693 = 2147375830
  • 233 + 2147375597 = 2147375830
  • 239 + 2147375591 = 2147375830
  • 263 + 2147375567 = 2147375830
  • 269 + 2147375561 = 2147375830
  • 359 + 2147375471 = 2147375830

Showing the first eight; more decompositions exist.
