Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474476, here are decompositions:

43 + 31474433 = 31474476
53 + 31474423 = 31474476
73 + 31474403 = 31474476
79 + 31474397 = 31474476
113 + 31474363 = 31474476
157 + 31474319 = 31474476
223 + 31474253 = 31474476
227 + 31474249 = 31474476

Showing the first eight; more decompositions exist.
