Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532170, here are decompositions:

3 + 31532167 = 31532170
29 + 31532141 = 31532170
53 + 31532117 = 31532170
107 + 31532063 = 31532170
149 + 31532021 = 31532170
167 + 31532003 = 31532170
239 + 31531931 = 31532170
353 + 31531817 = 31532170

Showing the first eight; more decompositions exist.
