Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737866, here are decompositions:

17 + 8737849 = 8737866
23 + 8737843 = 8737866
37 + 8737829 = 8737866
83 + 8737783 = 8737866
103 + 8737763 = 8737866
149 + 8737717 = 8737866
157 + 8737709 = 8737866
167 + 8737699 = 8737866

Showing the first eight; more decompositions exist.
