Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723936, here are decompositions:

3 + 8723933 = 8723936
7 + 8723929 = 8723936
37 + 8723899 = 8723936
43 + 8723893 = 8723936
103 + 8723833 = 8723936
229 + 8723707 = 8723936
283 + 8723653 = 8723936
367 + 8723569 = 8723936

Showing the first eight; more decompositions exist.
