Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690266, here are decompositions:

89 + 8690177 = 8690266
149 + 8690117 = 8690266
173 + 8690093 = 8690266
197 + 8690069 = 8690266
269 + 8689997 = 8690266
317 + 8689949 = 8690266
443 + 8689823 = 8690266
449 + 8689817 = 8690266

Showing the first eight; more decompositions exist.
