Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23120, here are decompositions:

3 + 23117 = 23120
61 + 23059 = 23120
67 + 23053 = 23120
79 + 23041 = 23120
103 + 23017 = 23120
109 + 23011 = 23120
127 + 22993 = 23120
157 + 22963 = 23120

Showing the first eight; more decompositions exist.
