Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527324, here are decompositions:

7 + 31527317 = 31527324
13 + 31527311 = 31527324
47 + 31527277 = 31527324
71 + 31527253 = 31527324
113 + 31527211 = 31527324
131 + 31527193 = 31527324
151 + 31527173 = 31527324
167 + 31527157 = 31527324

Showing the first eight; more decompositions exist.
