Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723158, here are decompositions:

167 + 8722991 = 8723158
281 + 8722877 = 8723158
317 + 8722841 = 8723158
359 + 8722799 = 8723158
401 + 8722757 = 8723158
419 + 8722739 = 8723158
617 + 8722541 = 8723158
641 + 8722517 = 8723158

Showing the first eight; more decompositions exist.
