Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166730, here are decompositions:

7 + 166723 = 166730
37 + 166693 = 166730
61 + 166669 = 166730
73 + 166657 = 166730
103 + 166627 = 166730
127 + 166603 = 166730
163 + 166567 = 166730
313 + 166417 = 166730

Showing the first eight; more decompositions exist.
