Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742298, here are decompositions:

101 + 8742197 = 8742298
137 + 8742161 = 8742298
239 + 8742059 = 8742298
311 + 8741987 = 8742298
347 + 8741951 = 8742298
431 + 8741867 = 8742298
557 + 8741741 = 8742298
599 + 8741699 = 8742298

Showing the first eight; more decompositions exist.
