Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66746, here are decompositions:

7 + 66739 = 66746
13 + 66733 = 66746
103 + 66643 = 66746
193 + 66553 = 66746
223 + 66523 = 66746
283 + 66463 = 66746
373 + 66373 = 66746
409 + 66337 = 66746

Showing the first eight; more decompositions exist.
