Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670900, here are decompositions:

13 + 8670887 = 8670900
31 + 8670869 = 8670900
37 + 8670863 = 8670900
89 + 8670811 = 8670900
109 + 8670791 = 8670900
127 + 8670773 = 8670900
149 + 8670751 = 8670900
157 + 8670743 = 8670900

Showing the first eight; more decompositions exist.
