Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737578, here are decompositions:

7 + 8737571 = 8737578
89 + 8737489 = 8737578
97 + 8737481 = 8737578
151 + 8737427 = 8737578
229 + 8737349 = 8737578
277 + 8737301 = 8737578
307 + 8737271 = 8737578
331 + 8737247 = 8737578

Showing the first eight; more decompositions exist.
