Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375020, here are decompositions:

  • 23 + 2147374997 = 2147375020
  • 173 + 2147374847 = 2147375020
  • 179 + 2147374841 = 2147375020
  • 233 + 2147374787 = 2147375020
  • 293 + 2147374727 = 2147375020
  • 347 + 2147374673 = 2147375020
  • 443 + 2147374577 = 2147375020
  • 683 + 2147374337 = 2147375020

Showing the first eight; more decompositions exist.
