Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731158, here are decompositions:

5 + 8731153 = 8731158
17 + 8731141 = 8731158
19 + 8731139 = 8731158
47 + 8731111 = 8731158
61 + 8731097 = 8731158
89 + 8731069 = 8731158
127 + 8731031 = 8731158
131 + 8731027 = 8731158

Showing the first eight; more decompositions exist.
