Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136960, here are decompositions:

11 + 136949 = 136960
17 + 136943 = 136960
71 + 136889 = 136960
101 + 136859 = 136960
149 + 136811 = 136960
191 + 136769 = 136960
227 + 136733 = 136960
233 + 136727 = 136960

Showing the first eight; more decompositions exist.
