Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758818, here are decompositions:

17 + 8758801 = 8758818
31 + 8758787 = 8758818
37 + 8758781 = 8758818
41 + 8758777 = 8758818
71 + 8758747 = 8758818
97 + 8758721 = 8758818
149 + 8758669 = 8758818
157 + 8758661 = 8758818

Showing the first eight; more decompositions exist.
