Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737398, here are decompositions:

41 + 8737357 = 8737398
97 + 8737301 = 8737398
127 + 8737271 = 8737398
149 + 8737249 = 8737398
151 + 8737247 = 8737398
199 + 8737199 = 8737398
269 + 8737129 = 8737398
281 + 8737117 = 8737398

Showing the first eight; more decompositions exist.
