Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147586960, here are decompositions:

  • 7 + 2147586953 = 2147586960
  • 11 + 2147586949 = 2147586960
  • 19 + 2147586941 = 2147586960
  • 41 + 2147586919 = 2147586960
  • 83 + 2147586877 = 2147586960
  • 137 + 2147586823 = 2147586960
  • 149 + 2147586811 = 2147586960
  • 173 + 2147586787 = 2147586960

Showing the first eight; more decompositions exist.
