Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72270, here are decompositions:

17 + 72253 = 72270
19 + 72251 = 72270
41 + 72229 = 72270
43 + 72227 = 72270
47 + 72223 = 72270
59 + 72211 = 72270
97 + 72173 = 72270
101 + 72169 = 72270

Showing the first eight; more decompositions exist.
