Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726556, here are decompositions:

23 + 8726533 = 8726556
29 + 8726527 = 8726556
89 + 8726467 = 8726556
107 + 8726449 = 8726556
109 + 8726447 = 8726556
173 + 8726383 = 8726556
193 + 8726363 = 8726556
197 + 8726359 = 8726556

Showing the first eight; more decompositions exist.
