Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532124, here are decompositions:

7 + 31532117 = 31532124
11 + 31532113 = 31532124
53 + 31532071 = 31532124
61 + 31532063 = 31532124
103 + 31532021 = 31532124
157 + 31531967 = 31532124
193 + 31531931 = 31532124
241 + 31531883 = 31532124

Showing the first eight; more decompositions exist.
