Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 159680, here are decompositions:

7 + 159673 = 159680
13 + 159667 = 159680
109 + 159571 = 159680
127 + 159553 = 159680
139 + 159541 = 159680
181 + 159499 = 159680
211 + 159469 = 159680
223 + 159457 = 159680

Showing the first eight; more decompositions exist.
