Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702838, here are decompositions:

5 + 8702833 = 8702838
17 + 8702821 = 8702838
19 + 8702819 = 8702838
61 + 8702777 = 8702838
107 + 8702731 = 8702838
139 + 8702699 = 8702838
149 + 8702689 = 8702838
191 + 8702647 = 8702838

Showing the first eight; more decompositions exist.
