Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450956, here are decompositions:

7 + 31450949 = 31450956
59 + 31450897 = 31450956
109 + 31450847 = 31450956
113 + 31450843 = 31450956
127 + 31450829 = 31450956
167 + 31450789 = 31450956
193 + 31450763 = 31450956
233 + 31450723 = 31450956

Showing the first eight; more decompositions exist.
