Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625824, here are decompositions:

3 + 8625821 = 8625824
13 + 8625811 = 8625824
37 + 8625787 = 8625824
271 + 8625553 = 8625824
283 + 8625541 = 8625824
307 + 8625517 = 8625824
331 + 8625493 = 8625824
373 + 8625451 = 8625824

Showing the first eight; more decompositions exist.
