Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532058, here are decompositions:

37 + 31532021 = 31532058
127 + 31531931 = 31532058
137 + 31531921 = 31532058
149 + 31531909 = 31532058
241 + 31531817 = 31532058
307 + 31531751 = 31532058
331 + 31531727 = 31532058
379 + 31531679 = 31532058

Showing the first eight; more decompositions exist.
