Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527348, here are decompositions:

5 + 31527343 = 31527348
31 + 31527317 = 31527348
37 + 31527311 = 31527348
71 + 31527277 = 31527348
101 + 31527247 = 31527348
137 + 31527211 = 31527348
157 + 31527191 = 31527348
191 + 31527157 = 31527348

Showing the first eight; more decompositions exist.
