Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690566, here are decompositions:

89 + 8690477 = 8690566
113 + 8690453 = 8690566
167 + 8690399 = 8690566
179 + 8690387 = 8690566
233 + 8690333 = 8690566
263 + 8690303 = 8690566
389 + 8690177 = 8690566
449 + 8690117 = 8690566

Showing the first eight; more decompositions exist.
