Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615496, here are decompositions:

7 + 31615489 = 31615496
13 + 31615483 = 31615496
19 + 31615477 = 31615496
67 + 31615429 = 31615496
79 + 31615417 = 31615496
97 + 31615399 = 31615496
163 + 31615333 = 31615496
223 + 31615273 = 31615496

Showing the first eight; more decompositions exist.
