Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715402, here are decompositions:

19 + 8715383 = 8715402
41 + 8715361 = 8715402
53 + 8715349 = 8715402
79 + 8715323 = 8715402
139 + 8715263 = 8715402
193 + 8715209 = 8715402
211 + 8715191 = 8715402
251 + 8715151 = 8715402

Showing the first eight; more decompositions exist.
