Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66072, here are decompositions:

5 + 66067 = 66072
31 + 66041 = 66072
43 + 66029 = 66072
79 + 65993 = 66072
89 + 65983 = 66072
109 + 65963 = 66072
151 + 65921 = 66072
173 + 65899 = 66072

Showing the first eight; more decompositions exist.
