Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55886, here are decompositions:

37 + 55849 = 55886
43 + 55843 = 55886
67 + 55819 = 55886
73 + 55813 = 55886
79 + 55807 = 55886
223 + 55663 = 55886
277 + 55609 = 55886
283 + 55603 = 55886

Showing the first eight; more decompositions exist.
