Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527474, here are decompositions:

61 + 31527413 = 31527474
67 + 31527407 = 31527474
131 + 31527343 = 31527474
151 + 31527323 = 31527474
157 + 31527317 = 31527474
163 + 31527311 = 31527474
197 + 31527277 = 31527474
227 + 31527247 = 31527474

Showing the first eight; more decompositions exist.
