Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723592, here are decompositions:

23 + 8723569 = 8723592
41 + 8723551 = 8723592
61 + 8723531 = 8723592
71 + 8723521 = 8723592
109 + 8723483 = 8723592
113 + 8723479 = 8723592
151 + 8723441 = 8723592
173 + 8723419 = 8723592

Showing the first eight; more decompositions exist.
