Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527444, here are decompositions:

31 + 31527413 = 31527444
37 + 31527407 = 31527444
101 + 31527343 = 31527444
127 + 31527317 = 31527444
167 + 31527277 = 31527444
191 + 31527253 = 31527444
197 + 31527247 = 31527444
211 + 31527233 = 31527444

Showing the first eight; more decompositions exist.
