Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723570, here are decompositions:

19 + 8723551 = 8723570
73 + 8723497 = 8723570
151 + 8723419 = 8723570
211 + 8723359 = 8723570
223 + 8723347 = 8723570
367 + 8723203 = 8723570
379 + 8723191 = 8723570
421 + 8723149 = 8723570

Showing the first eight; more decompositions exist.
