Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474606, here are decompositions:

5 + 31474601 = 31474606
29 + 31474577 = 31474606
47 + 31474559 = 31474606
173 + 31474433 = 31474606
263 + 31474343 = 31474606
353 + 31474253 = 31474606
389 + 31474217 = 31474606
563 + 31474043 = 31474606

Showing the first eight; more decompositions exist.
