Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613360, here are decompositions:

3 + 31613357 = 31613360
19 + 31613341 = 31613360
223 + 31613137 = 31613360
241 + 31613119 = 31613360
307 + 31613053 = 31613360
379 + 31612981 = 31613360
409 + 31612951 = 31613360
421 + 31612939 = 31613360

Showing the first eight; more decompositions exist.
