Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615602, here are decompositions:

13 + 31615589 = 31615602
19 + 31615583 = 31615602
59 + 31615543 = 31615602
113 + 31615489 = 31615602
131 + 31615471 = 31615602
163 + 31615439 = 31615602
173 + 31615429 = 31615602
199 + 31615403 = 31615602

Showing the first eight; more decompositions exist.
