Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474724, here are decompositions:

3 + 31474721 = 31474724
31 + 31474693 = 31474724
37 + 31474687 = 31474724
223 + 31474501 = 31474724
367 + 31474357 = 31474724
373 + 31474351 = 31474724
433 + 31474291 = 31474724
613 + 31474111 = 31474724

Showing the first eight; more decompositions exist.
