Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174778, here are decompositions:

5 + 174773 = 174778
11 + 174767 = 174778
17 + 174761 = 174778
29 + 174749 = 174778
41 + 174737 = 174778
179 + 174599 = 174778
251 + 174527 = 174778
311 + 174467 = 174778

Showing the first eight; more decompositions exist.
