Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73278, here are decompositions:

19 + 73259 = 73278
41 + 73237 = 73278
89 + 73189 = 73278
97 + 73181 = 73278
137 + 73141 = 73278
151 + 73127 = 73278
157 + 73121 = 73278
199 + 73079 = 73278

Showing the first eight; more decompositions exist.
