Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628122, here are decompositions:

73 + 8628049 = 8628122
103 + 8628019 = 8628122
211 + 8627911 = 8628122
229 + 8627893 = 8628122
271 + 8627851 = 8628122
313 + 8627809 = 8628122
409 + 8627713 = 8628122
421 + 8627701 = 8628122

Showing the first eight; more decompositions exist.
