Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723854, here are decompositions:

3 + 8723851 = 8723854
47 + 8723807 = 8723854
431 + 8723423 = 8723854
467 + 8723387 = 8723854
641 + 8723213 = 8723854
773 + 8723081 = 8723854
863 + 8722991 = 8723854
941 + 8722913 = 8723854

Showing the first eight; more decompositions exist.
