Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147443530, here are decompositions:

  • 7 + 2147443523 = 2147443530
  • 17 + 2147443513 = 2147443530
  • 59 + 2147443471 = 2147443530
  • 107 + 2147443423 = 2147443530
  • 109 + 2147443421 = 2147443530
  • 131 + 2147443399 = 2147443530
  • 139 + 2147443391 = 2147443530
  • 157 + 2147443373 = 2147443530

Showing the first eight; more decompositions exist.
