Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758928, here are decompositions:

7 + 8758921 = 8758928
37 + 8758891 = 8758928
67 + 8758861 = 8758928
109 + 8758819 = 8758928
127 + 8758801 = 8758928
151 + 8758777 = 8758928
181 + 8758747 = 8758928
331 + 8758597 = 8758928

Showing the first eight; more decompositions exist.
