Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613254, here are decompositions:

5 + 31613249 = 31613254
11 + 31613243 = 31613254
83 + 31613171 = 31613254
137 + 31613117 = 31613254
227 + 31613027 = 31613254
263 + 31612991 = 31613254
293 + 31612961 = 31613254
401 + 31612853 = 31613254

Showing the first eight; more decompositions exist.
