Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701970, here are decompositions:

19 + 8701951 = 8701970
37 + 8701933 = 8701970
97 + 8701873 = 8701970
157 + 8701813 = 8701970
181 + 8701789 = 8701970
223 + 8701747 = 8701970
229 + 8701741 = 8701970
241 + 8701729 = 8701970

Showing the first eight; more decompositions exist.
