Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613122, here are decompositions:

3 + 31613119 = 31613122
5 + 31613117 = 31613122
131 + 31612991 = 31613122
269 + 31612853 = 31613122
383 + 31612739 = 31613122
389 + 31612733 = 31613122
461 + 31612661 = 31613122
503 + 31612619 = 31613122

Showing the first eight; more decompositions exist.
