Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136540, here are decompositions:

3 + 136537 = 136540
17 + 136523 = 136540
29 + 136511 = 136540
59 + 136481 = 136540
137 + 136403 = 136540
167 + 136373 = 136540
179 + 136361 = 136540
197 + 136343 = 136540

Showing the first eight; more decompositions exist.
