Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 472, here are decompositions:

5 + 467 = 472
11 + 461 = 472
23 + 449 = 472
29 + 443 = 472
41 + 431 = 472
53 + 419 = 472
71 + 401 = 472
83 + 389 = 472

Showing the first eight; more decompositions exist.
