Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514394, here are decompositions:

97 + 31514297 = 31514394
103 + 31514291 = 31514394
127 + 31514267 = 31514394
173 + 31514221 = 31514394
251 + 31514143 = 31514394
281 + 31514113 = 31514394
293 + 31514101 = 31514394
313 + 31514081 = 31514394

Showing the first eight; more decompositions exist.
