Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 474, here are decompositions:

7 + 467 = 474
11 + 463 = 474
13 + 461 = 474
17 + 457 = 474
31 + 443 = 474
41 + 433 = 474
43 + 431 = 474
53 + 421 = 474

Showing the first eight; more decompositions exist.
