Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723906, here are decompositions:

3 + 8723903 = 8723906
7 + 8723899 = 8723906
13 + 8723893 = 8723906
19 + 8723887 = 8723906
73 + 8723833 = 8723906
199 + 8723707 = 8723906
229 + 8723677 = 8723906
313 + 8723593 = 8723906

Showing the first eight; more decompositions exist.
