Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594032, here are decompositions:

73 + 31593959 = 31594032
79 + 31593953 = 31594032
89 + 31593943 = 31594032
101 + 31593931 = 31594032
131 + 31593901 = 31594032
163 + 31593869 = 31594032
193 + 31593839 = 31594032
199 + 31593833 = 31594032

Showing the first eight; more decompositions exist.
