Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527356, here are decompositions:

13 + 31527343 = 31527356
79 + 31527277 = 31527356
103 + 31527253 = 31527356
109 + 31527247 = 31527356
163 + 31527193 = 31527356
199 + 31527157 = 31527356
457 + 31526899 = 31527356
463 + 31526893 = 31527356

Showing the first eight; more decompositions exist.
