Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723500, here are decompositions:

3 + 8723497 = 8723500
17 + 8723483 = 8723500
41 + 8723459 = 8723500
59 + 8723441 = 8723500
101 + 8723399 = 8723500
113 + 8723387 = 8723500
179 + 8723321 = 8723500
197 + 8723303 = 8723500

Showing the first eight; more decompositions exist.
