Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55638, here are decompositions:

5 + 55633 = 55638
7 + 55631 = 55638
17 + 55621 = 55638
19 + 55619 = 55638
29 + 55609 = 55638
59 + 55579 = 55638
97 + 55541 = 55638
109 + 55529 = 55638

Showing the first eight; more decompositions exist.
