Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171774, here are decompositions:

11 + 171763 = 171774
13 + 171761 = 171774
17 + 171757 = 171774
41 + 171733 = 171774
61 + 171713 = 171774
67 + 171707 = 171774
101 + 171673 = 171774
103 + 171671 = 171774

Showing the first eight; more decompositions exist.
