Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532074, here are decompositions:

3 + 31532071 = 31532074
11 + 31532063 = 31532074
53 + 31532021 = 31532074
71 + 31532003 = 31532074
107 + 31531967 = 31532074
191 + 31531883 = 31532074
257 + 31531817 = 31532074
347 + 31531727 = 31532074

Showing the first eight; more decompositions exist.
