Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615682, here are decompositions:

13 + 31615669 = 31615682
19 + 31615663 = 31615682
31 + 31615651 = 31615682
73 + 31615609 = 31615682
79 + 31615603 = 31615682
139 + 31615543 = 31615682
193 + 31615489 = 31615682
199 + 31615483 = 31615682

Showing the first eight; more decompositions exist.
