Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80166, here are decompositions:

13 + 80153 = 80166
17 + 80149 = 80166
19 + 80147 = 80166
59 + 80107 = 80166
89 + 80077 = 80166
127 + 80039 = 80166
167 + 79999 = 80166
179 + 79987 = 80166

Showing the first eight; more decompositions exist.
