Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625042, here are decompositions:

29 + 8625013 = 8625042
31 + 8625011 = 8625042
43 + 8624999 = 8625042
61 + 8624981 = 8625042
89 + 8624953 = 8625042
113 + 8624929 = 8625042
269 + 8624773 = 8625042
271 + 8624771 = 8625042

Showing the first eight; more decompositions exist.
