Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731166, here are decompositions:

13 + 8731153 = 8731166
97 + 8731069 = 8731166
127 + 8731039 = 8731166
139 + 8731027 = 8731166
277 + 8730889 = 8731166
307 + 8730859 = 8731166
373 + 8730793 = 8731166
547 + 8730619 = 8731166

Showing the first eight; more decompositions exist.
