Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494396, here are decompositions:

7 + 31494389 = 31494396
103 + 31494293 = 31494396
139 + 31494257 = 31494396
149 + 31494247 = 31494396
239 + 31494157 = 31494396
277 + 31494119 = 31494396
313 + 31494083 = 31494396
317 + 31494079 = 31494396

Showing the first eight; more decompositions exist.
