Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37638, here are decompositions:

5 + 37633 = 37638
19 + 37619 = 37638
31 + 37607 = 37638
47 + 37591 = 37638
59 + 37579 = 37638
67 + 37571 = 37638
71 + 37567 = 37638
89 + 37549 = 37638

Showing the first eight; more decompositions exist.
