Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147481848, here are decompositions:

  • 37 + 2147481811 = 2147481848
  • 277 + 2147481571 = 2147481848
  • 349 + 2147481499 = 2147481848
  • 601 + 2147481247 = 2147481848
  • 709 + 2147481139 = 2147481848
  • 829 + 2147481019 = 2147481848
  • 859 + 2147480989 = 2147481848
  • 877 + 2147480971 = 2147481848

Showing the first eight; more decompositions exist.
