Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686118, here are decompositions:

31 + 8686087 = 8686118
139 + 8685979 = 8686118
151 + 8685967 = 8686118
157 + 8685961 = 8686118
271 + 8685847 = 8686118
349 + 8685769 = 8686118
367 + 8685751 = 8686118
379 + 8685739 = 8686118

Showing the first eight; more decompositions exist.
