Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56390, here are decompositions:

7 + 56383 = 56390
13 + 56377 = 56390
31 + 56359 = 56390
79 + 56311 = 56390
127 + 56263 = 56390
151 + 56239 = 56390
181 + 56209 = 56390
193 + 56197 = 56390

Showing the first eight; more decompositions exist.
