Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66056, here are decompositions:

19 + 66037 = 66056
73 + 65983 = 66056
127 + 65929 = 66056
157 + 65899 = 66056
229 + 65827 = 66056
337 + 65719 = 66056
349 + 65707 = 66056
379 + 65677 = 66056

Showing the first eight; more decompositions exist.
