Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731194, here are decompositions:

7 + 8731187 = 8731194
41 + 8731153 = 8731194
53 + 8731141 = 8731194
83 + 8731111 = 8731194
97 + 8731097 = 8731194
163 + 8731031 = 8731194
167 + 8731027 = 8731194
211 + 8730983 = 8731194

Showing the first eight; more decompositions exist.
