Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103856, here are decompositions:

13 + 103843 = 103856
19 + 103837 = 103856
43 + 103813 = 103856
157 + 103699 = 103856
199 + 103657 = 103856
283 + 103573 = 103856
307 + 103549 = 103856
373 + 103483 = 103856

Showing the first eight; more decompositions exist.
