Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165774, here are decompositions:

53 + 165721 = 165774
61 + 165713 = 165774
67 + 165707 = 165774
71 + 165703 = 165774
73 + 165701 = 165774
101 + 165673 = 165774
107 + 165667 = 165774
157 + 165617 = 165774

Showing the first eight; more decompositions exist.
