Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543056, here are decompositions:

37 + 31543019 = 31543056
47 + 31543009 = 31543056
89 + 31542967 = 31543056
107 + 31542949 = 31543056
113 + 31542943 = 31543056
179 + 31542877 = 31543056
199 + 31542857 = 31543056
227 + 31542829 = 31543056

Showing the first eight; more decompositions exist.
