Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723960, here are decompositions:

13 + 8723947 = 8723960
31 + 8723929 = 8723960
61 + 8723899 = 8723960
67 + 8723893 = 8723960
73 + 8723887 = 8723960
109 + 8723851 = 8723960
127 + 8723833 = 8723960
139 + 8723821 = 8723960

Showing the first eight; more decompositions exist.
