Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66642, here are decompositions:

13 + 66629 = 66642
41 + 66601 = 66642
71 + 66571 = 66642
73 + 66569 = 66642
89 + 66553 = 66642
101 + 66541 = 66642
109 + 66533 = 66642
113 + 66529 = 66642

Showing the first eight; more decompositions exist.
