Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516596, here are decompositions:

29 + 31516567 = 31516596
37 + 31516559 = 31516596
53 + 31516543 = 31516596
73 + 31516523 = 31516596
103 + 31516493 = 31516596
113 + 31516483 = 31516596
127 + 31516469 = 31516596
173 + 31516423 = 31516596

Showing the first eight; more decompositions exist.
