Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80156, here are decompositions:

3 + 80153 = 80156
7 + 80149 = 80156
79 + 80077 = 80156
157 + 79999 = 80156
283 + 79873 = 80156
313 + 79843 = 80156
379 + 79777 = 80156
457 + 79699 = 80156

Showing the first eight; more decompositions exist.
