Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39778, here are decompositions:

17 + 39761 = 39778
29 + 39749 = 39778
59 + 39719 = 39778
107 + 39671 = 39778
197 + 39581 = 39778
227 + 39551 = 39778
257 + 39521 = 39778
269 + 39509 = 39778

Showing the first eight; more decompositions exist.
