Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613448, here are decompositions:

7 + 31613441 = 31613448
11 + 31613437 = 31613448
37 + 31613411 = 31613448
47 + 31613401 = 31613448
71 + 31613377 = 31613448
107 + 31613341 = 31613448
157 + 31613291 = 31613448
199 + 31613249 = 31613448

Showing the first eight; more decompositions exist.
