Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626904, here are decompositions:

3 + 8626901 = 8626904
43 + 8626861 = 8626904
73 + 8626831 = 8626904
103 + 8626801 = 8626904
127 + 8626777 = 8626904
157 + 8626747 = 8626904
283 + 8626621 = 8626904
397 + 8626507 = 8626904

Showing the first eight; more decompositions exist.
