Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8731198, here are decompositions:

11 + 8731187 = 8731198
59 + 8731139 = 8731198
89 + 8731109 = 8731198
101 + 8731097 = 8731198
167 + 8731031 = 8731198
251 + 8730947 = 8731198
269 + 8730929 = 8731198
317 + 8730881 = 8731198

Showing the first eight; more decompositions exist.
