Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123080, here are decompositions:

3 + 123077 = 123080
31 + 123049 = 123080
73 + 123007 = 123080
79 + 123001 = 123080
109 + 122971 = 123080
127 + 122953 = 123080
151 + 122929 = 123080
193 + 122887 = 123080

Showing the first eight; more decompositions exist.
