Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746438, here are decompositions:

11 + 8746427 = 8746438
47 + 8746391 = 8746438
59 + 8746379 = 8746438
137 + 8746301 = 8746438
167 + 8746271 = 8746438
179 + 8746259 = 8746438
401 + 8746037 = 8746438
509 + 8745929 = 8746438

Showing the first eight; more decompositions exist.
