Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494314, here are decompositions:

13 + 31494301 = 31494314
67 + 31494247 = 31494314
73 + 31494241 = 31494314
157 + 31494157 = 31494314
223 + 31494091 = 31494314
331 + 31493983 = 31494314
373 + 31493941 = 31494314
433 + 31493881 = 31494314

Showing the first eight; more decompositions exist.
