Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540056, here are decompositions:

43 + 31540013 = 31540056
47 + 31540009 = 31540056
89 + 31539967 = 31540056
167 + 31539889 = 31540056
193 + 31539863 = 31540056
199 + 31539857 = 31540056
239 + 31539817 = 31540056
293 + 31539763 = 31540056

Showing the first eight; more decompositions exist.
