Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690524, here are decompositions:

47 + 8690477 = 8690524
71 + 8690453 = 8690524
113 + 8690411 = 8690524
137 + 8690387 = 8690524
173 + 8690351 = 8690524
191 + 8690333 = 8690524
233 + 8690291 = 8690524
257 + 8690267 = 8690524

Showing the first eight; more decompositions exist.
