Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166776, here are decompositions:

37 + 166739 = 166776
53 + 166723 = 166776
73 + 166703 = 166776
83 + 166693 = 166776
97 + 166679 = 166776
107 + 166669 = 166776
109 + 166667 = 166776
149 + 166627 = 166776

Showing the first eight; more decompositions exist.
