Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474574, here are decompositions:

3 + 31474571 = 31474574
73 + 31474501 = 31474574
151 + 31474423 = 31474574
211 + 31474363 = 31474574
223 + 31474351 = 31474574
283 + 31474291 = 31474574
433 + 31474141 = 31474574
463 + 31474111 = 31474574

Showing the first eight; more decompositions exist.
