Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122154, here are decompositions:

5 + 122149 = 122154
7 + 122147 = 122154
23 + 122131 = 122154
37 + 122117 = 122154
73 + 122081 = 122154
101 + 122053 = 122154
103 + 122051 = 122154
113 + 122041 = 122154

Showing the first eight; more decompositions exist.
