Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749398, here are decompositions:

41 + 8749357 = 8749398
61 + 8749337 = 8749398
67 + 8749331 = 8749398
89 + 8749309 = 8749398
179 + 8749219 = 8749398
191 + 8749207 = 8749398
199 + 8749199 = 8749398
257 + 8749141 = 8749398

Showing the first eight; more decompositions exist.
