Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690506, here are decompositions:

17 + 8690489 = 8690506
29 + 8690477 = 8690506
53 + 8690453 = 8690506
107 + 8690399 = 8690506
173 + 8690333 = 8690506
239 + 8690267 = 8690506
389 + 8690117 = 8690506
443 + 8690063 = 8690506

Showing the first eight; more decompositions exist.
