Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527162, here are decompositions:

5 + 31527157 = 31527162
11 + 31527151 = 31527162
13 + 31527149 = 31527162
19 + 31527143 = 31527162
31 + 31527131 = 31527162
53 + 31527109 = 31527162
151 + 31527011 = 31527162
223 + 31526939 = 31527162

Showing the first eight; more decompositions exist.
