Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615622, here are decompositions:

13 + 31615609 = 31615622
19 + 31615603 = 31615622
79 + 31615543 = 31615622
139 + 31615483 = 31615622
151 + 31615471 = 31615622
193 + 31615429 = 31615622
223 + 31615399 = 31615622
349 + 31615273 = 31615622

Showing the first eight; more decompositions exist.
