Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8162, here are decompositions:

61 + 8101 = 8162
73 + 8089 = 8162
103 + 8059 = 8162
109 + 8053 = 8162
151 + 8011 = 8162
199 + 7963 = 8162
211 + 7951 = 8162
229 + 7933 = 8162

Showing the first eight; more decompositions exist.
