Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701872, here are decompositions:

19 + 8701853 = 8701872
59 + 8701813 = 8701872
61 + 8701811 = 8701872
83 + 8701789 = 8701872
131 + 8701741 = 8701872
149 + 8701723 = 8701872
163 + 8701709 = 8701872
229 + 8701643 = 8701872

Showing the first eight; more decompositions exist.
