Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527228, here are decompositions:

17 + 31527211 = 31527228
37 + 31527191 = 31527228
71 + 31527157 = 31527228
79 + 31527149 = 31527228
97 + 31527131 = 31527228
151 + 31527077 = 31527228
181 + 31527047 = 31527228
211 + 31527017 = 31527228

Showing the first eight; more decompositions exist.
