Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724164, here are decompositions:

3 + 8724161 = 8724164
37 + 8724127 = 8724164
151 + 8724013 = 8724164
271 + 8723893 = 8724164
277 + 8723887 = 8724164
313 + 8723851 = 8724164
331 + 8723833 = 8724164
433 + 8723731 = 8724164

Showing the first eight; more decompositions exist.
