Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136830, here are decompositions:

17 + 136813 = 136830
19 + 136811 = 136830
53 + 136777 = 136830
61 + 136769 = 136830
79 + 136751 = 136830
97 + 136733 = 136830
103 + 136727 = 136830
137 + 136693 = 136830

Showing the first eight; more decompositions exist.
