Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690500, here are decompositions:

11 + 8690489 = 8690500
23 + 8690477 = 8690500
47 + 8690453 = 8690500
89 + 8690411 = 8690500
101 + 8690399 = 8690500
113 + 8690387 = 8690500
149 + 8690351 = 8690500
167 + 8690333 = 8690500

Showing the first eight; more decompositions exist.
