Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160890, here are decompositions:

7 + 160883 = 160890
11 + 160879 = 160890
13 + 160877 = 160890
29 + 160861 = 160890
61 + 160829 = 160890
73 + 160817 = 160890
83 + 160807 = 160890
101 + 160789 = 160890

Showing the first eight; more decompositions exist.
