Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527148, here are decompositions:

5 + 31527143 = 31527148
17 + 31527131 = 31527148
41 + 31527107 = 31527148
71 + 31527077 = 31527148
101 + 31527047 = 31527148
131 + 31527017 = 31527148
137 + 31527011 = 31527148
227 + 31526921 = 31527148

Showing the first eight; more decompositions exist.
