Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66130, here are decompositions:

23 + 66107 = 66130
41 + 66089 = 66130
47 + 66083 = 66130
59 + 66071 = 66130
83 + 66047 = 66130
89 + 66041 = 66130
101 + 66029 = 66130
137 + 65993 = 66130

Showing the first eight; more decompositions exist.
