Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723838, here are decompositions:

5 + 8723833 = 8723838
17 + 8723821 = 8723838
31 + 8723807 = 8723838
107 + 8723731 = 8723838
131 + 8723707 = 8723838
199 + 8723639 = 8723838
229 + 8723609 = 8723838
269 + 8723569 = 8723838

Showing the first eight; more decompositions exist.
