Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613352, here are decompositions:

11 + 31613341 = 31613352
19 + 31613333 = 31613352
61 + 31613291 = 31613352
103 + 31613249 = 31613352
109 + 31613243 = 31613352
181 + 31613171 = 31613352
233 + 31613119 = 31613352
383 + 31612969 = 31613352

Showing the first eight; more decompositions exist.
