Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494318, here are decompositions:

17 + 31494301 = 31494318
61 + 31494257 = 31494318
71 + 31494247 = 31494318
139 + 31494179 = 31494318
157 + 31494161 = 31494318
199 + 31494119 = 31494318
227 + 31494091 = 31494318
239 + 31494079 = 31494318

Showing the first eight; more decompositions exist.
