Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66738, here are decompositions:

5 + 66733 = 66738
17 + 66721 = 66738
37 + 66701 = 66738
41 + 66697 = 66738
109 + 66629 = 66738
137 + 66601 = 66738
151 + 66587 = 66738
167 + 66571 = 66738

Showing the first eight; more decompositions exist.
