Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625840, here are decompositions:

7 + 8625833 = 8625840
19 + 8625821 = 8625840
29 + 8625811 = 8625840
31 + 8625809 = 8625840
53 + 8625787 = 8625840
107 + 8625733 = 8625840
131 + 8625709 = 8625840
151 + 8625689 = 8625840

Showing the first eight; more decompositions exist.
