Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723880, here are decompositions:

29 + 8723851 = 8723880
47 + 8723833 = 8723880
59 + 8723821 = 8723880
73 + 8723807 = 8723880
149 + 8723731 = 8723880
173 + 8723707 = 8723880
227 + 8723653 = 8723880
241 + 8723639 = 8723880

Showing the first eight; more decompositions exist.
