Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162684, here are decompositions:

7 + 162677 = 162684
13 + 162671 = 162684
43 + 162641 = 162684
61 + 162623 = 162684
73 + 162611 = 162684
83 + 162601 = 162684
107 + 162577 = 162684
127 + 162557 = 162684

Showing the first eight; more decompositions exist.
