Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80172, here are decompositions:

5 + 80167 = 80172
19 + 80153 = 80172
23 + 80149 = 80172
31 + 80141 = 80172
61 + 80111 = 80172
101 + 80071 = 80172
151 + 80021 = 80172
173 + 79999 = 80172

Showing the first eight; more decompositions exist.
