Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8740438, here are decompositions:

11 + 8740427 = 8740438
71 + 8740367 = 8740438
101 + 8740337 = 8740438
107 + 8740331 = 8740438
137 + 8740301 = 8740438
149 + 8740289 = 8740438
251 + 8740187 = 8740438
269 + 8740169 = 8740438

Showing the first eight; more decompositions exist.
