Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655418, here are decompositions:

17 + 8655401 = 8655418
47 + 8655371 = 8655418
131 + 8655287 = 8655418
251 + 8655167 = 8655418
269 + 8655149 = 8655418
347 + 8655071 = 8655418
389 + 8655029 = 8655418
521 + 8654897 = 8655418

Showing the first eight; more decompositions exist.
