Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516514, here are decompositions:

13 + 31516501 = 31516514
31 + 31516483 = 31516514
103 + 31516411 = 31516514
157 + 31516357 = 31516514
181 + 31516333 = 31516514
277 + 31516237 = 31516514
313 + 31516201 = 31516514
331 + 31516183 = 31516514

Showing the first eight; more decompositions exist.
