Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615634, here are decompositions:

31 + 31615603 = 31615634
151 + 31615483 = 31615634
157 + 31615477 = 31615634
163 + 31615471 = 31615634
313 + 31615321 = 31615634
397 + 31615237 = 31615634
571 + 31615063 = 31615634
691 + 31614943 = 31615634

Showing the first eight; more decompositions exist.
