Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80154, here are decompositions:

5 + 80149 = 80154
7 + 80147 = 80154
13 + 80141 = 80154
43 + 80111 = 80154
47 + 80107 = 80154
83 + 80071 = 80154
103 + 80051 = 80154
157 + 79997 = 80154

Showing the first eight; more decompositions exist.
