Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618886, here are decompositions:

7 + 8618879 = 8618886
19 + 8618867 = 8618886
53 + 8618833 = 8618886
97 + 8618789 = 8618886
103 + 8618783 = 8618886
127 + 8618759 = 8618886
137 + 8618749 = 8618886
139 + 8618747 = 8618886

Showing the first eight; more decompositions exist.
