Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166774, here are decompositions:

71 + 166703 = 166774
107 + 166667 = 166774
131 + 166643 = 166774
173 + 166601 = 166774
233 + 166541 = 166774
317 + 166457 = 166774
617 + 166157 = 166774
743 + 166031 = 166774

Showing the first eight; more decompositions exist.
