Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516662, here are decompositions:

29 + 31516633 = 31516662
31 + 31516631 = 31516662
43 + 31516619 = 31516662
59 + 31516603 = 31516662
103 + 31516559 = 31516662
139 + 31516523 = 31516662
179 + 31516483 = 31516662
193 + 31516469 = 31516662

Showing the first eight; more decompositions exist.
