Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3628, here are decompositions:

5 + 3623 = 3628
11 + 3617 = 3628
47 + 3581 = 3628
71 + 3557 = 3628
89 + 3539 = 3628
101 + 3527 = 3628
137 + 3491 = 3628
167 + 3461 = 3628

Showing the first eight; more decompositions exist.
