Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147435228, here are decompositions:

  • 67 + 2147435161 = 2147435228
  • 79 + 2147435149 = 2147435228
  • 157 + 2147435071 = 2147435228
  • 349 + 2147434879 = 2147435228
  • 457 + 2147434771 = 2147435228
  • 541 + 2147434687 = 2147435228
  • 577 + 2147434651 = 2147435228
  • 709 + 2147434519 = 2147435228

Showing the first eight; more decompositions exist.
