Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700242, here are decompositions:

3 + 8700239 = 8700242
73 + 8700169 = 8700242
163 + 8700079 = 8700242
211 + 8700031 = 8700242
223 + 8700019 = 8700242
241 + 8700001 = 8700242
283 + 8699959 = 8700242
349 + 8699893 = 8700242

Showing the first eight; more decompositions exist.
