Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723932, here are decompositions:

3 + 8723929 = 8723932
11 + 8723921 = 8723932
23 + 8723909 = 8723932
29 + 8723903 = 8723932
53 + 8723879 = 8723932
293 + 8723639 = 8723932
401 + 8723531 = 8723932
449 + 8723483 = 8723932

Showing the first eight; more decompositions exist.
