Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162802, here are decompositions:

11 + 162791 = 162802
23 + 162779 = 162802
53 + 162749 = 162802
71 + 162731 = 162802
89 + 162713 = 162802
131 + 162671 = 162802
173 + 162629 = 162802
179 + 162623 = 162802

Showing the first eight; more decompositions exist.
