Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723938, here are decompositions:

5 + 8723933 = 8723938
17 + 8723921 = 8723938
29 + 8723909 = 8723938
59 + 8723879 = 8723938
131 + 8723807 = 8723938
149 + 8723789 = 8723938
479 + 8723459 = 8723938
617 + 8723321 = 8723938

Showing the first eight; more decompositions exist.
