Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628126, here are decompositions:

5 + 8628121 = 8628126
19 + 8628107 = 8628126
29 + 8628097 = 8628126
107 + 8628019 = 8628126
109 + 8628017 = 8628126
139 + 8627987 = 8628126
149 + 8627977 = 8628126
173 + 8627953 = 8628126

Showing the first eight; more decompositions exist.
