Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66470, here are decompositions:

3 + 66467 = 66470
7 + 66463 = 66470
13 + 66457 = 66470
67 + 66403 = 66470
97 + 66373 = 66470
109 + 66361 = 66470
127 + 66343 = 66470
199 + 66271 = 66470

Showing the first eight; more decompositions exist.
