Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72312, here are decompositions:

5 + 72307 = 72312
41 + 72271 = 72312
43 + 72269 = 72312
59 + 72253 = 72312
61 + 72251 = 72312
83 + 72229 = 72312
89 + 72223 = 72312
101 + 72211 = 72312

Showing the first eight; more decompositions exist.
