Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613384, here are decompositions:

7 + 31613377 = 31613384
43 + 31613341 = 31613384
157 + 31613227 = 31613384
193 + 31613191 = 31613384
241 + 31613143 = 31613384
277 + 31613107 = 31613384
331 + 31613053 = 31613384
433 + 31612951 = 31613384

Showing the first eight; more decompositions exist.
