Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723560, here are decompositions:

29 + 8723531 = 8723560
101 + 8723459 = 8723560
137 + 8723423 = 8723560
173 + 8723387 = 8723560
239 + 8723321 = 8723560
257 + 8723303 = 8723560
317 + 8723243 = 8723560
347 + 8723213 = 8723560

Showing the first eight; more decompositions exist.
