Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613338, here are decompositions:

5 + 31613333 = 31613338
47 + 31613291 = 31613338
89 + 31613249 = 31613338
167 + 31613171 = 31613338
311 + 31613027 = 31613338
347 + 31612991 = 31613338
599 + 31612739 = 31613338
677 + 31612661 = 31613338

Showing the first eight; more decompositions exist.
