Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761398, here are decompositions:

59 + 8761339 = 8761398
71 + 8761327 = 8761398
101 + 8761297 = 8761398
109 + 8761289 = 8761398
229 + 8761169 = 8761398
241 + 8761157 = 8761398
257 + 8761141 = 8761398
281 + 8761117 = 8761398

Showing the first eight; more decompositions exist.
