Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72304, here are decompositions:

17 + 72287 = 72304
53 + 72251 = 72304
83 + 72221 = 72304
131 + 72173 = 72304
137 + 72167 = 72304
227 + 72077 = 72304
251 + 72053 = 72304
257 + 72047 = 72304

Showing the first eight; more decompositions exist.
