Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743856, here are decompositions:

3 + 8743853 = 8743856
13 + 8743843 = 8743856
19 + 8743837 = 8743856
103 + 8743753 = 8743856
109 + 8743747 = 8743856
139 + 8743717 = 8743856
223 + 8743633 = 8743856
307 + 8743549 = 8743856

Showing the first eight; more decompositions exist.
