Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931860, here are decompositions:

11 + 931849 = 931860
23 + 931837 = 931860
71 + 931789 = 931860
79 + 931781 = 931860
103 + 931757 = 931860
109 + 931751 = 931860
113 + 931747 = 931860
131 + 931729 = 931860

Showing the first eight; more decompositions exist.
