Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731116, here are decompositions:

5 + 8731111 = 8731116
7 + 8731109 = 8731116
13 + 8731103 = 8731116
19 + 8731097 = 8731116
47 + 8731069 = 8731116
89 + 8731027 = 8731116
139 + 8730977 = 8731116
167 + 8730949 = 8731116

Showing the first eight; more decompositions exist.
