Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127146, here are decompositions:

7 + 127139 = 127146
13 + 127133 = 127146
23 + 127123 = 127146
43 + 127103 = 127146
67 + 127079 = 127146
109 + 127037 = 127146
113 + 127033 = 127146
157 + 126989 = 127146

Showing the first eight; more decompositions exist.
