Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159770, here are decompositions:

7 + 159763 = 159770
31 + 159739 = 159770
73 + 159697 = 159770
97 + 159673 = 159770
103 + 159667 = 159770
139 + 159631 = 159770
181 + 159589 = 159770
199 + 159571 = 159770

Showing the first eight; more decompositions exist.
