Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31613226, here are decompositions:

83 + 31613143 = 31613226
89 + 31613137 = 31613226
107 + 31613119 = 31613226
109 + 31613117 = 31613226
173 + 31613053 = 31613226
199 + 31613027 = 31613226
257 + 31612969 = 31613226
313 + 31612913 = 31613226

Showing the first eight; more decompositions exist.
