Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615514, here are decompositions:

31 + 31615483 = 31615514
37 + 31615477 = 31615514
43 + 31615471 = 31615514
97 + 31615417 = 31615514
181 + 31615333 = 31615514
193 + 31615321 = 31615514
241 + 31615273 = 31615514
277 + 31615237 = 31615514

Showing the first eight; more decompositions exist.
