Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723800, here are decompositions:

11 + 8723789 = 8723800
191 + 8723609 = 8723800
269 + 8723531 = 8723800
317 + 8723483 = 8723800
359 + 8723441 = 8723800
401 + 8723399 = 8723800
479 + 8723321 = 8723800
557 + 8723243 = 8723800

Showing the first eight; more decompositions exist.
