Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66122, here are decompositions:

13 + 66109 = 66122
19 + 66103 = 66122
139 + 65983 = 66122
193 + 65929 = 66122
223 + 65899 = 66122
241 + 65881 = 66122
271 + 65851 = 66122
283 + 65839 = 66122

Showing the first eight; more decompositions exist.
