Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163660, here are decompositions:

17 + 163643 = 163660
23 + 163637 = 163660
47 + 163613 = 163660
59 + 163601 = 163660
173 + 163487 = 163660
179 + 163481 = 163660
191 + 163469 = 163660
227 + 163433 = 163660

Showing the first eight; more decompositions exist.
