Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147434628, here are decompositions:

  • 67 + 2147434561 = 2147434628
  • 109 + 2147434519 = 2147434628
  • 151 + 2147434477 = 2147434628
  • 337 + 2147434291 = 2147434628
  • 349 + 2147434279 = 2147434628
  • 487 + 2147434141 = 2147434628
  • 1051 + 2147433577 = 2147434628
  • 1069 + 2147433559 = 2147434628

Showing the first eight; more decompositions exist.
