Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147564018, here are decompositions:

  • 7 + 2147564011 = 2147564018
  • 151 + 2147563867 = 2147564018
  • 157 + 2147563861 = 2147564018
  • 181 + 2147563837 = 2147564018
  • 199 + 2147563819 = 2147564018
  • 211 + 2147563807 = 2147564018
  • 277 + 2147563741 = 2147564018
  • 331 + 2147563687 = 2147564018

Showing the first eight; more decompositions exist.
