Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626912, here are decompositions:

11 + 8626901 = 8626912
71 + 8626841 = 8626912
89 + 8626823 = 8626912
101 + 8626811 = 8626912
149 + 8626763 = 8626912
179 + 8626733 = 8626912
269 + 8626643 = 8626912
383 + 8626529 = 8626912

Showing the first eight; more decompositions exist.
