Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613418, here are decompositions:

7 + 31613411 = 31613418
17 + 31613401 = 31613418
19 + 31613399 = 31613418
41 + 31613377 = 31613418
61 + 31613357 = 31613418
127 + 31613291 = 31613418
191 + 31613227 = 31613418
227 + 31613191 = 31613418

Showing the first eight; more decompositions exist.
