Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 432, here are decompositions:

11 + 421 = 432
13 + 419 = 432
23 + 409 = 432
31 + 401 = 432
43 + 389 = 432
53 + 379 = 432
59 + 373 = 432
73 + 359 = 432

Showing the first eight; more decompositions exist.
