Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532086, here are decompositions:

23 + 31532063 = 31532086
83 + 31532003 = 31532086
269 + 31531817 = 31532086
359 + 31531727 = 31532086
419 + 31531667 = 31532086
563 + 31531523 = 31532086
683 + 31531403 = 31532086
947 + 31531139 = 31532086

Showing the first eight; more decompositions exist.
