Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615662, here are decompositions:

11 + 31615651 = 31615662
53 + 31615609 = 31615662
59 + 31615603 = 31615662
73 + 31615589 = 31615662
79 + 31615583 = 31615662
173 + 31615489 = 31615662
179 + 31615483 = 31615662
191 + 31615471 = 31615662

Showing the first eight; more decompositions exist.
