Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 179778, here are decompositions:

29 + 179749 = 179778
41 + 179737 = 179778
59 + 179719 = 179778
61 + 179717 = 179778
89 + 179689 = 179778
107 + 179671 = 179778
127 + 179651 = 179778
197 + 179581 = 179778

Showing the first eight; more decompositions exist.
