Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701018, here are decompositions:

5 + 8701013 = 8701018
17 + 8701001 = 8701018
71 + 8700947 = 8701018
107 + 8700911 = 8701018
149 + 8700869 = 8701018
191 + 8700827 = 8701018
251 + 8700767 = 8701018
419 + 8700599 = 8701018

Showing the first eight; more decompositions exist.
