Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170778, here are decompositions:

5 + 170773 = 170778
11 + 170767 = 170778
17 + 170761 = 170778
19 + 170759 = 170778
29 + 170749 = 170778
37 + 170741 = 170778
67 + 170711 = 170778
71 + 170707 = 170778

Showing the first eight; more decompositions exist.
