Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456056, here are decompositions:

43 + 31456013 = 31456056
53 + 31456003 = 31456056
97 + 31455959 = 31456056
109 + 31455947 = 31456056
127 + 31455929 = 31456056
167 + 31455889 = 31456056
179 + 31455877 = 31456056
197 + 31455859 = 31456056

Showing the first eight; more decompositions exist.
