Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80728, here are decompositions:

41 + 80687 = 80728
47 + 80681 = 80728
59 + 80669 = 80728
71 + 80657 = 80728
101 + 80627 = 80728
107 + 80621 = 80728
191 + 80537 = 80728
239 + 80489 = 80728

Showing the first eight; more decompositions exist.
