Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615476, here are decompositions:

5 + 31615471 = 31615476
37 + 31615439 = 31615476
47 + 31615429 = 31615476
59 + 31615417 = 31615476
73 + 31615403 = 31615476
163 + 31615313 = 31615476
239 + 31615237 = 31615476
283 + 31615193 = 31615476

Showing the first eight; more decompositions exist.
