Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634220, here are decompositions:

17 + 8634203 = 8634220
41 + 8634179 = 8634220
47 + 8634173 = 8634220
59 + 8634161 = 8634220
83 + 8634137 = 8634220
113 + 8634107 = 8634220
167 + 8634053 = 8634220
239 + 8633981 = 8634220

Showing the first eight; more decompositions exist.
