Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80138, here are decompositions:

31 + 80107 = 80138
61 + 80077 = 80138
67 + 80071 = 80138
139 + 79999 = 80138
151 + 79987 = 80138
199 + 79939 = 80138
271 + 79867 = 80138
277 + 79861 = 80138

Showing the first eight; more decompositions exist.
