Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628692, here are decompositions:

31 + 8628661 = 8628692
139 + 8628553 = 8628692
199 + 8628493 = 8628692
211 + 8628481 = 8628692
229 + 8628463 = 8628692
271 + 8628421 = 8628692
421 + 8628271 = 8628692
571 + 8628121 = 8628692

Showing the first eight; more decompositions exist.
