Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723582, here are decompositions:

13 + 8723569 = 8723582
31 + 8723551 = 8723582
61 + 8723521 = 8723582
103 + 8723479 = 8723582
163 + 8723419 = 8723582
223 + 8723359 = 8723582
229 + 8723353 = 8723582
271 + 8723311 = 8723582

Showing the first eight; more decompositions exist.
