Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66070, here are decompositions:

3 + 66067 = 66070
23 + 66047 = 66070
29 + 66041 = 66070
41 + 66029 = 66070
89 + 65981 = 66070
107 + 65963 = 66070
113 + 65957 = 66070
149 + 65921 = 66070

Showing the first eight; more decompositions exist.
