Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723612, here are decompositions:

3 + 8723609 = 8723612
19 + 8723593 = 8723612
43 + 8723569 = 8723612
61 + 8723551 = 8723612
193 + 8723419 = 8723612
409 + 8723203 = 8723612
421 + 8723191 = 8723612
463 + 8723149 = 8723612

Showing the first eight; more decompositions exist.
