Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532166, here are decompositions:

53 + 31532113 = 31532166
103 + 31532063 = 31532166
163 + 31532003 = 31532166
199 + 31531967 = 31532166
257 + 31531909 = 31532166
283 + 31531883 = 31532166
349 + 31531817 = 31532166
353 + 31531813 = 31532166

Showing the first eight; more decompositions exist.
