Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761518, here are decompositions:

11 + 8761507 = 8761518
61 + 8761457 = 8761518
79 + 8761439 = 8761518
89 + 8761429 = 8761518
179 + 8761339 = 8761518
191 + 8761327 = 8761518
229 + 8761289 = 8761518
239 + 8761279 = 8761518

Showing the first eight; more decompositions exist.
