Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66564, here are decompositions:

11 + 66553 = 66564
23 + 66541 = 66564
31 + 66533 = 66564
41 + 66523 = 66564
73 + 66491 = 66564
97 + 66467 = 66564
101 + 66463 = 66564
107 + 66457 = 66564

Showing the first eight; more decompositions exist.
