Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621192, here are decompositions:

3 + 8621189 = 8621192
103 + 8621089 = 8621192
109 + 8621083 = 8621192
199 + 8620993 = 8621192
241 + 8620951 = 8621192
331 + 8620861 = 8621192
571 + 8620621 = 8621192
823 + 8620369 = 8621192

Showing the first eight; more decompositions exist.
