Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625872, here are decompositions:

19 + 8625853 = 8625872
61 + 8625811 = 8625872
139 + 8625733 = 8625872
163 + 8625709 = 8625872
223 + 8625649 = 8625872
313 + 8625559 = 8625872
331 + 8625541 = 8625872
379 + 8625493 = 8625872

Showing the first eight; more decompositions exist.
