Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31546956, here are decompositions:

19 + 31546937 = 31546956
43 + 31546913 = 31546956
47 + 31546909 = 31546956
109 + 31546847 = 31546956
113 + 31546843 = 31546956
139 + 31546817 = 31546956
149 + 31546807 = 31546956
157 + 31546799 = 31546956

Showing the first eight; more decompositions exist.
