Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72364, here are decompositions:

11 + 72353 = 72364
23 + 72341 = 72364
113 + 72251 = 72364
137 + 72227 = 72364
191 + 72173 = 72364
197 + 72167 = 72364
263 + 72101 = 72364
311 + 72053 = 72364

Showing the first eight; more decompositions exist.
