Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514434, here are decompositions:

5 + 31514429 = 31514434
11 + 31514423 = 31514434
137 + 31514297 = 31514434
167 + 31514267 = 31514434
173 + 31514261 = 31514434
353 + 31514081 = 31514434
467 + 31513967 = 31514434
491 + 31513943 = 31514434

Showing the first eight; more decompositions exist.
