Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625584, here are decompositions:

31 + 8625553 = 8625584
43 + 8625541 = 8625584
67 + 8625517 = 8625584
241 + 8625343 = 8625584
271 + 8625313 = 8625584
283 + 8625301 = 8625584
337 + 8625247 = 8625584
397 + 8625187 = 8625584

Showing the first eight; more decompositions exist.
