Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136530, here are decompositions:

7 + 136523 = 136530
11 + 136519 = 136530
19 + 136511 = 136530
29 + 136501 = 136530
47 + 136483 = 136530
59 + 136471 = 136530
67 + 136463 = 136530
83 + 136447 = 136530

Showing the first eight; more decompositions exist.
