Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634372, here are decompositions:

13 + 8634359 = 8634372
73 + 8634299 = 8634372
113 + 8634259 = 8634372
139 + 8634233 = 8634372
193 + 8634179 = 8634372
199 + 8634173 = 8634372
211 + 8634161 = 8634372
233 + 8634139 = 8634372

Showing the first eight; more decompositions exist.
