Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 13136, here are decompositions:

37 + 13099 = 13136
43 + 13093 = 13136
73 + 13063 = 13136
103 + 13033 = 13136
127 + 13009 = 13136
157 + 12979 = 13136
163 + 12973 = 13136
229 + 12907 = 13136

Showing the first eight; more decompositions exist.
