Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136986, here are decompositions:

7 + 136979 = 136986
13 + 136973 = 136986
23 + 136963 = 136986
37 + 136949 = 136986
43 + 136943 = 136986
89 + 136897 = 136986
97 + 136889 = 136986
103 + 136883 = 136986

Showing the first eight; more decompositions exist.
