Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506976, here are decompositions:

3 + 31506973 = 31506976
47 + 31506929 = 31506976
89 + 31506887 = 31506976
167 + 31506809 = 31506976
227 + 31506749 = 31506976
233 + 31506743 = 31506976
257 + 31506719 = 31506976
617 + 31506359 = 31506976

Showing the first eight; more decompositions exist.
