Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532082, here are decompositions:

11 + 31532071 = 31532082
19 + 31532063 = 31532082
61 + 31532021 = 31532082
79 + 31532003 = 31532082
151 + 31531931 = 31532082
173 + 31531909 = 31532082
199 + 31531883 = 31532082
269 + 31531813 = 31532082

Showing the first eight; more decompositions exist.
