Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761386, here are decompositions:

47 + 8761339 = 8761386
59 + 8761327 = 8761386
83 + 8761303 = 8761386
89 + 8761297 = 8761386
97 + 8761289 = 8761386
107 + 8761279 = 8761386
149 + 8761237 = 8761386
173 + 8761213 = 8761386

Showing the first eight; more decompositions exist.
