Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702828, here are decompositions:

7 + 8702821 = 8702828
97 + 8702731 = 8702828
139 + 8702689 = 8702828
181 + 8702647 = 8702828
241 + 8702587 = 8702828
271 + 8702557 = 8702828
331 + 8702497 = 8702828
397 + 8702431 = 8702828

Showing the first eight; more decompositions exist.
