Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72064, here are decompositions:

11 + 72053 = 72064
17 + 72047 = 72064
71 + 71993 = 72064
101 + 71963 = 72064
131 + 71933 = 72064
197 + 71867 = 72064
227 + 71837 = 72064
257 + 71807 = 72064

Showing the first eight; more decompositions exist.
