Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527414, here are decompositions:

7 + 31527407 = 31527414
71 + 31527343 = 31527414
97 + 31527317 = 31527414
103 + 31527311 = 31527414
137 + 31527277 = 31527414
167 + 31527247 = 31527414
181 + 31527233 = 31527414
223 + 31527191 = 31527414

Showing the first eight; more decompositions exist.
