Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8622418, here are decompositions:

5 + 8622413 = 8622418
59 + 8622359 = 8622418
131 + 8622287 = 8622418
227 + 8622191 = 8622418
281 + 8622137 = 8622418
347 + 8622071 = 8622418
401 + 8622017 = 8622418
479 + 8621939 = 8622418

Showing the first eight; more decompositions exist.
