Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80786, here are decompositions:

3 + 80783 = 80786
7 + 80779 = 80786
37 + 80749 = 80786
73 + 80713 = 80786
103 + 80683 = 80786
109 + 80677 = 80786
157 + 80629 = 80786
229 + 80557 = 80786

Showing the first eight; more decompositions exist.
