Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628042, here are decompositions:

11 + 8628031 = 8628042
23 + 8628019 = 8628042
89 + 8627953 = 8628042
103 + 8627939 = 8628042
131 + 8627911 = 8628042
139 + 8627903 = 8628042
149 + 8627893 = 8628042
191 + 8627851 = 8628042

Showing the first eight; more decompositions exist.
