Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473170, here are decompositions:

  • 19 + 2147473151 = 2147473170
  • 43 + 2147473127 = 2147473170
  • 53 + 2147473117 = 2147473170
  • 109 + 2147473061 = 2147473170
  • 211 + 2147472959 = 2147473170
  • 277 + 2147472893 = 2147473170
  • 307 + 2147472863 = 2147473170
  • 373 + 2147472797 = 2147473170

Showing the first eight; more decompositions exist.
