Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8724464, here are decompositions:

3 + 8724461 = 8724464
43 + 8724421 = 8724464
163 + 8724301 = 8724464
181 + 8724283 = 8724464
211 + 8724253 = 8724464
223 + 8724241 = 8724464
241 + 8724223 = 8724464
283 + 8724181 = 8724464

Showing the first eight; more decompositions exist.
