Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516526, here are decompositions:

3 + 31516523 = 31516526
7 + 31516519 = 31516526
43 + 31516483 = 31516526
103 + 31516423 = 31516526
193 + 31516333 = 31516526
199 + 31516327 = 31516526
229 + 31516297 = 31516526
337 + 31516189 = 31516526

Showing the first eight; more decompositions exist.
