Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726904, here are decompositions:

31 + 8726873 = 8726904
41 + 8726863 = 8726904
101 + 8726803 = 8726904
103 + 8726801 = 8726904
127 + 8726777 = 8726904
167 + 8726737 = 8726904
181 + 8726723 = 8726904
191 + 8726713 = 8726904

Showing the first eight; more decompositions exist.
