Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615482, here are decompositions:

5 + 31615477 = 31615482
11 + 31615471 = 31615482
43 + 31615439 = 31615482
53 + 31615429 = 31615482
79 + 31615403 = 31615482
83 + 31615399 = 31615482
139 + 31615343 = 31615482
149 + 31615333 = 31615482

Showing the first eight; more decompositions exist.
