Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156330, here are decompositions:

11 + 156319 = 156330
23 + 156307 = 156330
61 + 156269 = 156330
71 + 156259 = 156330
73 + 156257 = 156330
89 + 156241 = 156330
101 + 156229 = 156330
103 + 156227 = 156330

Showing the first eight; more decompositions exist.
