Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66626, here are decompositions:

73 + 66553 = 66626
97 + 66529 = 66626
103 + 66523 = 66626
127 + 66499 = 66626
163 + 66463 = 66626
223 + 66403 = 66626
283 + 66343 = 66626
457 + 66169 = 66626

Showing the first eight; more decompositions exist.
