Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731324, here are decompositions:

3 + 8731321 = 8731324
11 + 8731313 = 8731324
23 + 8731301 = 8731324
47 + 8731277 = 8731324
113 + 8731211 = 8731324
137 + 8731187 = 8731324
227 + 8731097 = 8731324
293 + 8731031 = 8731324

Showing the first eight; more decompositions exist.
