Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700402, here are decompositions:

19 + 8700383 = 8700402
41 + 8700361 = 8700402
103 + 8700299 = 8700402
149 + 8700253 = 8700402
163 + 8700239 = 8700402
233 + 8700169 = 8700402
241 + 8700161 = 8700402
281 + 8700121 = 8700402

Showing the first eight; more decompositions exist.
