Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516562, here are decompositions:

3 + 31516559 = 31516562
19 + 31516543 = 31516562
43 + 31516519 = 31516562
61 + 31516501 = 31516562
79 + 31516483 = 31516562
139 + 31516423 = 31516562
151 + 31516411 = 31516562
229 + 31516333 = 31516562

Showing the first eight; more decompositions exist.
