Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611628, here are decompositions:

31 + 8611597 = 8611628
79 + 8611549 = 8611628
97 + 8611531 = 8611628
127 + 8611501 = 8611628
229 + 8611399 = 8611628
271 + 8611357 = 8611628
307 + 8611321 = 8611628
331 + 8611297 = 8611628

Showing the first eight; more decompositions exist.
