Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66176, here are decompositions:

3 + 66173 = 66176
7 + 66169 = 66176
67 + 66109 = 66176
73 + 66103 = 66176
109 + 66067 = 66176
139 + 66037 = 66176
193 + 65983 = 66176
277 + 65899 = 66176

Showing the first eight; more decompositions exist.
