Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55730, here are decompositions:

13 + 55717 = 55730
19 + 55711 = 55730
67 + 55663 = 55730
97 + 55633 = 55730
109 + 55621 = 55730
127 + 55603 = 55730
151 + 55579 = 55730
229 + 55501 = 55730

Showing the first eight; more decompositions exist.
