Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532148, here are decompositions:

7 + 31532141 = 31532148
31 + 31532117 = 31532148
59 + 31532089 = 31532148
127 + 31532021 = 31532148
181 + 31531967 = 31532148
227 + 31531921 = 31532148
239 + 31531909 = 31532148
331 + 31531817 = 31532148

Showing the first eight; more decompositions exist.
