Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3626, here are decompositions:

3 + 3623 = 3626
13 + 3613 = 3626
19 + 3607 = 3626
43 + 3583 = 3626
67 + 3559 = 3626
79 + 3547 = 3626
97 + 3529 = 3626
109 + 3517 = 3626

Showing the first eight; more decompositions exist.
