Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3642, here are decompositions:

5 + 3637 = 3642
11 + 3631 = 3642
19 + 3623 = 3642
29 + 3613 = 3642
59 + 3583 = 3642
61 + 3581 = 3642
71 + 3571 = 3642
83 + 3559 = 3642

Showing the first eight; more decompositions exist.
