Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723964, here are decompositions:

13 + 8723951 = 8723964
17 + 8723947 = 8723964
31 + 8723933 = 8723964
43 + 8723921 = 8723964
61 + 8723903 = 8723964
71 + 8723893 = 8723964
113 + 8723851 = 8723964
131 + 8723833 = 8723964

Showing the first eight; more decompositions exist.
