Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80778, here are decompositions:

17 + 80761 = 80778
29 + 80749 = 80778
31 + 80747 = 80778
41 + 80737 = 80778
97 + 80681 = 80778
101 + 80677 = 80778
107 + 80671 = 80778
109 + 80669 = 80778

Showing the first eight; more decompositions exist.
