Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527336, here are decompositions:

13 + 31527323 = 31527336
19 + 31527317 = 31527336
59 + 31527277 = 31527336
83 + 31527253 = 31527336
89 + 31527247 = 31527336
103 + 31527233 = 31527336
163 + 31527173 = 31527336
179 + 31527157 = 31527336

Showing the first eight; more decompositions exist.
