Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625554, here are decompositions:

13 + 8625541 = 8625554
37 + 8625517 = 8625554
61 + 8625493 = 8625554
103 + 8625451 = 8625554
211 + 8625343 = 8625554
241 + 8625313 = 8625554
307 + 8625247 = 8625554
367 + 8625187 = 8625554

Showing the first eight; more decompositions exist.
