Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160690, here are decompositions:

3 + 160687 = 160690
41 + 160649 = 160690
53 + 160637 = 160690
71 + 160619 = 160690
107 + 160583 = 160690
137 + 160553 = 160690
149 + 160541 = 160690
191 + 160499 = 160690

Showing the first eight; more decompositions exist.
