Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474612, here are decompositions:

11 + 31474601 = 31474612
41 + 31474571 = 31474612
53 + 31474559 = 31474612
131 + 31474481 = 31474612
179 + 31474433 = 31474612
269 + 31474343 = 31474612
293 + 31474319 = 31474612
311 + 31474301 = 31474612

Showing the first eight; more decompositions exist.
