Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80148, here are decompositions:

7 + 80141 = 80148
37 + 80111 = 80148
41 + 80107 = 80148
71 + 80077 = 80148
97 + 80051 = 80148
109 + 80039 = 80148
127 + 80021 = 80148
149 + 79999 = 80148

Showing the first eight; more decompositions exist.
