Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701900, here are decompositions:

17 + 8701883 = 8701900
23 + 8701877 = 8701900
29 + 8701871 = 8701900
47 + 8701853 = 8701900
89 + 8701811 = 8701900
191 + 8701709 = 8701900
197 + 8701703 = 8701900
257 + 8701643 = 8701900

Showing the first eight; more decompositions exist.
