Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731126, here are decompositions:

17 + 8731109 = 8731126
23 + 8731103 = 8731126
29 + 8731097 = 8731126
149 + 8730977 = 8731126
179 + 8730947 = 8731126
197 + 8730929 = 8731126
233 + 8730893 = 8731126
263 + 8730863 = 8731126

Showing the first eight; more decompositions exist.
