Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625978, here are decompositions:

5 + 8625973 = 8625978
17 + 8625961 = 8625978
19 + 8625959 = 8625978
89 + 8625889 = 8625978
157 + 8625821 = 8625978
167 + 8625811 = 8625978
191 + 8625787 = 8625978
269 + 8625709 = 8625978

Showing the first eight; more decompositions exist.
