Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742198, here are decompositions:

5 + 8742193 = 8742198
11 + 8742187 = 8742198
29 + 8742169 = 8742198
37 + 8742161 = 8742198
41 + 8742157 = 8742198
131 + 8742067 = 8742198
139 + 8742059 = 8742198
211 + 8741987 = 8742198

Showing the first eight; more decompositions exist.
