Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8745198, here are decompositions:

29 + 8745169 = 8745198
37 + 8745161 = 8745198
79 + 8745119 = 8745198
97 + 8745101 = 8745198
101 + 8745097 = 8745198
127 + 8745071 = 8745198
131 + 8745067 = 8745198
167 + 8745031 = 8745198

Showing the first eight; more decompositions exist.
