Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702500, here are decompositions:

3 + 8702497 = 8702500
11 + 8702489 = 8702500
17 + 8702483 = 8702500
41 + 8702459 = 8702500
89 + 8702411 = 8702500
113 + 8702387 = 8702500
167 + 8702333 = 8702500
173 + 8702327 = 8702500

Showing the first eight; more decompositions exist.
