Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723506, here are decompositions:

23 + 8723483 = 8723506
47 + 8723459 = 8723506
83 + 8723423 = 8723506
107 + 8723399 = 8723506
263 + 8723243 = 8723506
293 + 8723213 = 8723506
383 + 8723123 = 8723506
443 + 8723063 = 8723506

Showing the first eight; more decompositions exist.
