Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156516, here are decompositions:

5 + 156511 = 156516
23 + 156493 = 156516
29 + 156487 = 156516
79 + 156437 = 156516
97 + 156419 = 156516
163 + 156353 = 156516
197 + 156319 = 156516
257 + 156259 = 156516

Showing the first eight; more decompositions exist.
