Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701818, here are decompositions:

5 + 8701813 = 8701818
7 + 8701811 = 8701818
29 + 8701789 = 8701818
61 + 8701757 = 8701818
71 + 8701747 = 8701818
89 + 8701729 = 8701818
109 + 8701709 = 8701818
197 + 8701621 = 8701818

Showing the first eight; more decompositions exist.
