Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 17774, here are decompositions:

13 + 17761 = 17774
37 + 17737 = 17774
61 + 17713 = 17774
67 + 17707 = 17774
151 + 17623 = 17774
193 + 17581 = 17774
223 + 17551 = 17774
277 + 17497 = 17774

Showing the first eight; more decompositions exist.
