Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516676, here are decompositions:

7 + 31516669 = 31516676
43 + 31516633 = 31516676
73 + 31516603 = 31516676
109 + 31516567 = 31516676
157 + 31516519 = 31516676
193 + 31516483 = 31516676
349 + 31516327 = 31516676
379 + 31516297 = 31516676

Showing the first eight; more decompositions exist.
