Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726878, here are decompositions:

5 + 8726873 = 8726878
29 + 8726849 = 8726878
89 + 8726789 = 8726878
101 + 8726777 = 8726878
179 + 8726699 = 8726878
191 + 8726687 = 8726878
431 + 8726447 = 8726878
521 + 8726357 = 8726878

Showing the first eight; more decompositions exist.
