Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162860, here are decompositions:

7 + 162853 = 162860
13 + 162847 = 162860
31 + 162829 = 162860
37 + 162823 = 162860
73 + 162787 = 162860
109 + 162751 = 162860
151 + 162709 = 162860
157 + 162703 = 162860

Showing the first eight; more decompositions exist.
