Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127152, here are decompositions:

13 + 127139 = 127152
19 + 127133 = 127152
29 + 127123 = 127152
71 + 127081 = 127152
73 + 127079 = 127152
101 + 127051 = 127152
163 + 126989 = 127152
191 + 126961 = 127152

Showing the first eight; more decompositions exist.
