Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725866, here are decompositions:

43 + 8725823 = 8725866
53 + 8725813 = 8725866
67 + 8725799 = 8725866
109 + 8725757 = 8725866
167 + 8725699 = 8725866
197 + 8725669 = 8725866
223 + 8725643 = 8725866
239 + 8725627 = 8725866

Showing the first eight; more decompositions exist.
