Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726832, here are decompositions:

29 + 8726803 = 8726832
31 + 8726801 = 8726832
43 + 8726789 = 8726832
71 + 8726761 = 8726832
73 + 8726759 = 8726832
109 + 8726723 = 8726832
199 + 8726633 = 8726832
263 + 8726569 = 8726832

Showing the first eight; more decompositions exist.
