Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3728, here are decompositions:

19 + 3709 = 3728
31 + 3697 = 3728
37 + 3691 = 3728
97 + 3631 = 3728
157 + 3571 = 3728
181 + 3547 = 3728
199 + 3529 = 3728
211 + 3517 = 3728

Showing the first eight; more decompositions exist.
