Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723644, here are decompositions:

5 + 8723639 = 8723644
113 + 8723531 = 8723644
257 + 8723387 = 8723644
401 + 8723243 = 8723644
431 + 8723213 = 8723644
521 + 8723123 = 8723644
563 + 8723081 = 8723644
653 + 8722991 = 8723644

Showing the first eight; more decompositions exist.
