Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523374, here are decompositions:

107 + 31523267 = 31523374
131 + 31523243 = 31523374
137 + 31523237 = 31523374
167 + 31523207 = 31523374
173 + 31523201 = 31523374
263 + 31523111 = 31523374
293 + 31523081 = 31523374
347 + 31523027 = 31523374

Showing the first eight; more decompositions exist.
