Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522814, here are decompositions:

67 + 31522747 = 31522814
97 + 31522717 = 31522814
151 + 31522663 = 31522814
157 + 31522657 = 31522814
181 + 31522633 = 31522814
223 + 31522591 = 31522814
373 + 31522441 = 31522814
457 + 31522357 = 31522814

Showing the first eight; more decompositions exist.
