Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443886, here are decompositions:

  • 97 + 2147443789 = 2147443886
  • 127 + 2147443759 = 2147443886
  • 139 + 2147443747 = 2147443886
  • 157 + 2147443729 = 2147443886
  • 283 + 2147443603 = 2147443886
  • 307 + 2147443579 = 2147443886
  • 349 + 2147443537 = 2147443886
  • 373 + 2147443513 = 2147443886

Showing the first eight; more decompositions exist.
