Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72136, here are decompositions:

47 + 72089 = 72136
59 + 72077 = 72136
83 + 72053 = 72136
89 + 72047 = 72136
137 + 71999 = 72136
149 + 71987 = 72136
173 + 71963 = 72136
227 + 71909 = 72136

Showing the first eight; more decompositions exist.
