Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615670, here are decompositions:

7 + 31615663 = 31615670
19 + 31615651 = 31615670
61 + 31615609 = 31615670
67 + 31615603 = 31615670
127 + 31615543 = 31615670
181 + 31615489 = 31615670
193 + 31615477 = 31615670
199 + 31615471 = 31615670

Showing the first eight; more decompositions exist.
