Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576056, here are decompositions:

7 + 31576049 = 31576056
19 + 31576037 = 31576056
47 + 31576009 = 31576056
53 + 31576003 = 31576056
139 + 31575917 = 31576056
157 + 31575899 = 31576056
163 + 31575893 = 31576056
179 + 31575877 = 31576056

Showing the first eight; more decompositions exist.
