Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740558, here are decompositions:

17 + 8740541 = 8740558
41 + 8740517 = 8740558
131 + 8740427 = 8740558
191 + 8740367 = 8740558
227 + 8740331 = 8740558
257 + 8740301 = 8740558
269 + 8740289 = 8740558
389 + 8740169 = 8740558

Showing the first eight; more decompositions exist.
