Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55760, here are decompositions:

43 + 55717 = 55760
79 + 55681 = 55760
97 + 55663 = 55760
127 + 55633 = 55760
139 + 55621 = 55760
151 + 55609 = 55760
157 + 55603 = 55760
181 + 55579 = 55760

Showing the first eight; more decompositions exist.
