Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166770, here are decompositions:

29 + 166741 = 166770
31 + 166739 = 166770
47 + 166723 = 166770
67 + 166703 = 166770
101 + 166669 = 166770
103 + 166667 = 166770
113 + 166657 = 166770
127 + 166643 = 166770

Showing the first eight; more decompositions exist.
