Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588056, here are decompositions:

37 + 31588019 = 31588056
53 + 31588003 = 31588056
107 + 31587949 = 31588056
113 + 31587943 = 31588056
163 + 31587893 = 31588056
179 + 31587877 = 31588056
197 + 31587859 = 31588056
239 + 31587817 = 31588056

Showing the first eight; more decompositions exist.
