Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758398, here are decompositions:

7 + 8758391 = 8758398
37 + 8758361 = 8758398
59 + 8758339 = 8758398
71 + 8758327 = 8758398
109 + 8758289 = 8758398
179 + 8758219 = 8758398
197 + 8758201 = 8758398
199 + 8758199 = 8758398

Showing the first eight; more decompositions exist.
