Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55784, here are decompositions:

67 + 55717 = 55784
73 + 55711 = 55784
103 + 55681 = 55784
151 + 55633 = 55784
163 + 55621 = 55784
181 + 55603 = 55784
283 + 55501 = 55784
373 + 55411 = 55784

Showing the first eight; more decompositions exist.
