Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491616, here are decompositions:

  • 7 + 2147491609 = 2147491616
  • 13 + 2147491603 = 2147491616
  • 19 + 2147491597 = 2147491616
  • 43 + 2147491573 = 2147491616
  • 73 + 2147491543 = 2147491616
  • 79 + 2147491537 = 2147491616
  • 139 + 2147491477 = 2147491616
  • 199 + 2147491417 = 2147491616

Showing the first eight; more decompositions exist.
