Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 123186, here are decompositions:

17 + 123169 = 123186
43 + 123143 = 123186
59 + 123127 = 123186
73 + 123113 = 123186
103 + 123083 = 123186
109 + 123077 = 123186
127 + 123059 = 123186
137 + 123049 = 123186

Showing the first eight; more decompositions exist.
