Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182778, here are decompositions:

5 + 182773 = 182778
31 + 182747 = 182778
67 + 182711 = 182778
97 + 182681 = 182778
137 + 182641 = 182778
139 + 182639 = 182778
151 + 182627 = 182778
179 + 182599 = 182778

Showing the first eight; more decompositions exist.
