Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625578, here are decompositions:

19 + 8625559 = 8625578
37 + 8625541 = 8625578
61 + 8625517 = 8625578
127 + 8625451 = 8625578
229 + 8625349 = 8625578
277 + 8625301 = 8625578
331 + 8625247 = 8625578
349 + 8625229 = 8625578

Showing the first eight; more decompositions exist.
