Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55790, here are decompositions:

3 + 55787 = 55790
73 + 55717 = 55790
79 + 55711 = 55790
109 + 55681 = 55790
127 + 55663 = 55790
151 + 55639 = 55790
157 + 55633 = 55790
181 + 55609 = 55790

Showing the first eight; more decompositions exist.
