Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 632, here are decompositions:

13 + 619 = 632
19 + 613 = 632
31 + 601 = 632
61 + 571 = 632
109 + 523 = 632
193 + 439 = 632
199 + 433 = 632
211 + 421 = 632

Showing the first eight; more decompositions exist.
