Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474512, here are decompositions:

11 + 31474501 = 31474512
23 + 31474489 = 31474512
31 + 31474481 = 31474512
79 + 31474433 = 31474512
89 + 31474423 = 31474512
109 + 31474403 = 31474512
149 + 31474363 = 31474512
193 + 31474319 = 31474512

Showing the first eight; more decompositions exist.
