Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655412, here are decompositions:

11 + 8655401 = 8655412
41 + 8655371 = 8655412
149 + 8655263 = 8655412
239 + 8655173 = 8655412
263 + 8655149 = 8655412
383 + 8655029 = 8655412
401 + 8655011 = 8655412
431 + 8654981 = 8655412

Showing the first eight; more decompositions exist.
