Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474708, here are decompositions:

17 + 31474691 = 31474708
107 + 31474601 = 31474708
131 + 31474577 = 31474708
137 + 31474571 = 31474708
149 + 31474559 = 31474708
227 + 31474481 = 31474708
311 + 31474397 = 31474708
389 + 31474319 = 31474708

Showing the first eight; more decompositions exist.
