Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152778, here are decompositions:

11 + 152767 = 152778
61 + 152717 = 152778
97 + 152681 = 152778
107 + 152671 = 152778
137 + 152641 = 152778
139 + 152639 = 152778
149 + 152629 = 152778
179 + 152599 = 152778

Showing the first eight; more decompositions exist.
