Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628088, here are decompositions:

11 + 8628077 = 8628088
71 + 8628017 = 8628088
101 + 8627987 = 8628088
149 + 8627939 = 8628088
179 + 8627909 = 8628088
191 + 8627897 = 8628088
281 + 8627807 = 8628088
311 + 8627777 = 8628088

Showing the first eight; more decompositions exist.
