Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123072, here are decompositions:

13 + 123059 = 123072
23 + 123049 = 123072
41 + 123031 = 123072
71 + 123001 = 123072
101 + 122971 = 123072
109 + 122963 = 123072
151 + 122921 = 123072
181 + 122891 = 123072

Showing the first eight; more decompositions exist.
