Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160840, here are decompositions:

11 + 160829 = 160840
23 + 160817 = 160840
59 + 160781 = 160840
83 + 160757 = 160840
89 + 160751 = 160840
101 + 160739 = 160840
131 + 160709 = 160840
191 + 160649 = 160840

Showing the first eight; more decompositions exist.
