Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 166626, here are decompositions:

7 + 166619 = 166626
13 + 166613 = 166626
17 + 166609 = 166626
23 + 166603 = 166626
29 + 166597 = 166626
59 + 166567 = 166626
139 + 166487 = 166626
197 + 166429 = 166626

Showing the first eight; more decompositions exist.
