Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613348, here are decompositions:

7 + 31613341 = 31613348
157 + 31613191 = 31613348
211 + 31613137 = 31613348
229 + 31613119 = 31613348
241 + 31613107 = 31613348
367 + 31612981 = 31613348
379 + 31612969 = 31613348
397 + 31612951 = 31613348

Showing the first eight; more decompositions exist.
