Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136980, here are decompositions:

7 + 136973 = 136980
17 + 136963 = 136980
29 + 136951 = 136980
31 + 136949 = 136980
37 + 136943 = 136980
83 + 136897 = 136980
97 + 136883 = 136980
101 + 136879 = 136980

Showing the first eight; more decompositions exist.
