Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628418, here are decompositions:

11 + 8628407 = 8628418
41 + 8628377 = 8628418
59 + 8628359 = 8628418
257 + 8628161 = 8628418
269 + 8628149 = 8628418
311 + 8628107 = 8628418
401 + 8628017 = 8628418
431 + 8627987 = 8628418

Showing the first eight; more decompositions exist.
