Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613394, here are decompositions:

11 + 31613383 = 31613394
17 + 31613377 = 31613394
37 + 31613357 = 31613394
53 + 31613341 = 31613394
61 + 31613333 = 31613394
103 + 31613291 = 31613394
151 + 31613243 = 31613394
167 + 31613227 = 31613394

Showing the first eight; more decompositions exist.
