Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702742, here are decompositions:

11 + 8702731 = 8702742
43 + 8702699 = 8702742
53 + 8702689 = 8702742
79 + 8702663 = 8702742
149 + 8702593 = 8702742
151 + 8702591 = 8702742
173 + 8702569 = 8702742
199 + 8702543 = 8702742

Showing the first eight; more decompositions exist.
