Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628524, here are decompositions:

31 + 8628493 = 8628524
43 + 8628481 = 8628524
61 + 8628463 = 8628524
103 + 8628421 = 8628524
337 + 8628187 = 8628524
367 + 8628157 = 8628524
547 + 8627977 = 8628524
571 + 8627953 = 8628524

Showing the first eight; more decompositions exist.
