Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749198, here are decompositions:

47 + 8749151 = 8749198
71 + 8749127 = 8749198
149 + 8749049 = 8749198
179 + 8749019 = 8749198
191 + 8749007 = 8749198
197 + 8749001 = 8749198
317 + 8748881 = 8749198
431 + 8748767 = 8749198

Showing the first eight; more decompositions exist.
