Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456122, here are decompositions:

23 + 31456099 = 31456122
29 + 31456093 = 31456122
43 + 31456079 = 31456122
101 + 31456021 = 31456122
109 + 31456013 = 31456122
163 + 31455959 = 31456122
193 + 31455929 = 31456122
233 + 31455889 = 31456122

Showing the first eight; more decompositions exist.
