Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752878, here are decompositions:

7 + 8752871 = 8752878
31 + 8752847 = 8752878
61 + 8752817 = 8752878
97 + 8752781 = 8752878
107 + 8752771 = 8752878
109 + 8752769 = 8752878
137 + 8752741 = 8752878
181 + 8752697 = 8752878

Showing the first eight; more decompositions exist.
