Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55644, here are decompositions:

5 + 55639 = 55644
11 + 55633 = 55644
13 + 55631 = 55644
23 + 55621 = 55644
41 + 55603 = 55644
97 + 55547 = 55644
103 + 55541 = 55644
157 + 55487 = 55644

Showing the first eight; more decompositions exist.
