Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527354, here are decompositions:

11 + 31527343 = 31527354
31 + 31527323 = 31527354
37 + 31527317 = 31527354
43 + 31527311 = 31527354
101 + 31527253 = 31527354
107 + 31527247 = 31527354
163 + 31527191 = 31527354
181 + 31527173 = 31527354

Showing the first eight; more decompositions exist.
