Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615608, here are decompositions:

5 + 31615603 = 31615608
19 + 31615589 = 31615608
131 + 31615477 = 31615608
137 + 31615471 = 31615608
179 + 31615429 = 31615608
191 + 31615417 = 31615608
379 + 31615229 = 31615608
397 + 31615211 = 31615608

Showing the first eight; more decompositions exist.
