Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527502, here are decompositions:

3 + 31527499 = 31527502
5 + 31527497 = 31527502
11 + 31527491 = 31527502
89 + 31527413 = 31527502
113 + 31527389 = 31527502
179 + 31527323 = 31527502
191 + 31527311 = 31527502
269 + 31527233 = 31527502

Showing the first eight; more decompositions exist.
