Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740198, here are decompositions:

11 + 8740187 = 8740198
29 + 8740169 = 8740198
41 + 8740157 = 8740198
59 + 8740139 = 8740198
101 + 8740097 = 8740198
281 + 8739917 = 8740198
347 + 8739851 = 8740198
431 + 8739767 = 8740198

Showing the first eight; more decompositions exist.
