Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147502836, here are decompositions:

  • 79 + 2147502757 = 2147502836
  • 163 + 2147502673 = 2147502836
  • 223 + 2147502613 = 2147502836
  • 313 + 2147502523 = 2147502836
  • 397 + 2147502439 = 2147502836
  • 439 + 2147502397 = 2147502836
  • 499 + 2147502337 = 2147502836
  • 823 + 2147502013 = 2147502836

Showing the first eight; more decompositions exist.
