Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80688, here are decompositions:

5 + 80683 = 80688
7 + 80681 = 80688
11 + 80677 = 80688
17 + 80671 = 80688
19 + 80669 = 80688
31 + 80657 = 80688
37 + 80651 = 80688
59 + 80629 = 80688

Showing the first eight; more decompositions exist.
