Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147556038, here are decompositions:

  • 37 + 2147556001 = 2147556038
  • 109 + 2147555929 = 2147556038
  • 139 + 2147555899 = 2147556038
  • 157 + 2147555881 = 2147556038
  • 241 + 2147555797 = 2147556038
  • 349 + 2147555689 = 2147556038
  • 409 + 2147555629 = 2147556038
  • 457 + 2147555581 = 2147556038

Showing the first eight; more decompositions exist.
