Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628154, here are decompositions:

5 + 8628149 = 8628154
23 + 8628131 = 8628154
47 + 8628107 = 8628154
137 + 8628017 = 8628154
167 + 8627987 = 8628154
251 + 8627903 = 8628154
257 + 8627897 = 8628154
347 + 8627807 = 8628154

Showing the first eight; more decompositions exist.
