Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731266, here are decompositions:

17 + 8731249 = 8731266
53 + 8731213 = 8731266
79 + 8731187 = 8731266
113 + 8731153 = 8731266
127 + 8731139 = 8731266
157 + 8731109 = 8731266
163 + 8731103 = 8731266
197 + 8731069 = 8731266

Showing the first eight; more decompositions exist.
