Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634340, here are decompositions:

41 + 8634299 = 8634340
89 + 8634251 = 8634340
107 + 8634233 = 8634340
137 + 8634203 = 8634340
167 + 8634173 = 8634340
179 + 8634161 = 8634340
233 + 8634107 = 8634340
263 + 8634077 = 8634340

Showing the first eight; more decompositions exist.
