Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 176780, here are decompositions:

3 + 176777 = 176780
67 + 176713 = 176780
103 + 176677 = 176780
139 + 176641 = 176780
151 + 176629 = 176780
181 + 176599 = 176780
223 + 176557 = 176780
229 + 176551 = 176780

Showing the first eight; more decompositions exist.
