Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690532, here are decompositions:

43 + 8690489 = 8690532
79 + 8690453 = 8690532
173 + 8690359 = 8690532
181 + 8690351 = 8690532
199 + 8690333 = 8690532
229 + 8690303 = 8690532
239 + 8690293 = 8690532
241 + 8690291 = 8690532

Showing the first eight; more decompositions exist.
