Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 136872, here are decompositions:

11 + 136861 = 136872
13 + 136859 = 136872
23 + 136849 = 136872
31 + 136841 = 136872
59 + 136813 = 136872
61 + 136811 = 136872
103 + 136769 = 136872
139 + 136733 = 136872

Showing the first eight; more decompositions exist.
