Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527252, here are decompositions:

5 + 31527247 = 31527252
19 + 31527233 = 31527252
41 + 31527211 = 31527252
59 + 31527193 = 31527252
61 + 31527191 = 31527252
79 + 31527173 = 31527252
101 + 31527151 = 31527252
103 + 31527149 = 31527252

Showing the first eight; more decompositions exist.
