Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80112, here are decompositions:

5 + 80107 = 80112
41 + 80071 = 80112
61 + 80051 = 80112
73 + 80039 = 80112
113 + 79999 = 80112
139 + 79973 = 80112
173 + 79939 = 80112
211 + 79901 = 80112

Showing the first eight; more decompositions exist.
