Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 135860, here are decompositions:

19 + 135841 = 135860
31 + 135829 = 135860
61 + 135799 = 135860
73 + 135787 = 135860
79 + 135781 = 135860
103 + 135757 = 135860
139 + 135721 = 135860
163 + 135697 = 135860

Showing the first eight; more decompositions exist.
