Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628174, here are decompositions:

13 + 8628161 = 8628174
17 + 8628157 = 8628174
43 + 8628131 = 8628174
53 + 8628121 = 8628174
67 + 8628107 = 8628174
97 + 8628077 = 8628174
157 + 8628017 = 8628174
167 + 8628007 = 8628174

Showing the first eight; more decompositions exist.
