Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162804, here are decompositions:

13 + 162791 = 162804
17 + 162787 = 162804
53 + 162751 = 162804
73 + 162731 = 162804
101 + 162703 = 162804
113 + 162691 = 162804
127 + 162677 = 162804
163 + 162641 = 162804

Showing the first eight; more decompositions exist.
