Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723900, here are decompositions:

7 + 8723893 = 8723900
13 + 8723887 = 8723900
67 + 8723833 = 8723900
79 + 8723821 = 8723900
193 + 8723707 = 8723900
223 + 8723677 = 8723900
307 + 8723593 = 8723900
331 + 8723569 = 8723900

Showing the first eight; more decompositions exist.
