Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152618, here are decompositions:

19 + 152599 = 152618
79 + 152539 = 152618
157 + 152461 = 152618
199 + 152419 = 152618
211 + 152407 = 152618
229 + 152389 = 152618
241 + 152377 = 152618
307 + 152311 = 152618

Showing the first eight; more decompositions exist.
