Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506996, here are decompositions:

19 + 31506977 = 31506996
23 + 31506973 = 31506996
47 + 31506949 = 31506996
67 + 31506929 = 31506996
89 + 31506907 = 31506996
109 + 31506887 = 31506996
167 + 31506829 = 31506996
173 + 31506823 = 31506996

Showing the first eight; more decompositions exist.
