Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474666, here are decompositions:

89 + 31474577 = 31474666
107 + 31474559 = 31474666
233 + 31474433 = 31474666
263 + 31474403 = 31474666
269 + 31474397 = 31474666
347 + 31474319 = 31474666
359 + 31474307 = 31474666
449 + 31474217 = 31474666

Showing the first eight; more decompositions exist.
