Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147396956, here are decompositions:

  • 53 + 2147396903 = 2147396956
  • 59 + 2147396897 = 2147396956
  • 137 + 2147396819 = 2147396956
  • 149 + 2147396807 = 2147396956
  • 197 + 2147396759 = 2147396956
  • 269 + 2147396687 = 2147396956
  • 347 + 2147396609 = 2147396956
  • 443 + 2147396513 = 2147396956

Showing the first eight; more decompositions exist.
