Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701856, here are decompositions:

3 + 8701853 = 8701856
43 + 8701813 = 8701856
67 + 8701789 = 8701856
109 + 8701747 = 8701856
127 + 8701729 = 8701856
199 + 8701657 = 8701856
337 + 8701519 = 8701856
349 + 8701507 = 8701856

Showing the first eight; more decompositions exist.
