Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532038, here are decompositions:

17 + 31532021 = 31532038
71 + 31531967 = 31532038
107 + 31531931 = 31532038
311 + 31531727 = 31532038
359 + 31531679 = 31532038
389 + 31531649 = 31532038
617 + 31531421 = 31532038
821 + 31531217 = 31532038

Showing the first eight; more decompositions exist.
