Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55928, here are decompositions:

7 + 55921 = 55928
31 + 55897 = 55928
79 + 55849 = 55928
109 + 55819 = 55928
211 + 55717 = 55928
307 + 55621 = 55928
349 + 55579 = 55928
487 + 55441 = 55928

Showing the first eight; more decompositions exist.
