Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670418, here are decompositions:

11 + 8670407 = 8670418
47 + 8670371 = 8670418
137 + 8670281 = 8670418
179 + 8670239 = 8670418
227 + 8670191 = 8670418
311 + 8670107 = 8670418
347 + 8670071 = 8670418
389 + 8670029 = 8670418

Showing the first eight; more decompositions exist.
