Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723404, here are decompositions:

5 + 8723399 = 8723404
17 + 8723387 = 8723404
83 + 8723321 = 8723404
101 + 8723303 = 8723404
191 + 8723213 = 8723404
281 + 8723123 = 8723404
491 + 8722913 = 8723404
563 + 8722841 = 8723404

Showing the first eight; more decompositions exist.
