Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655568, here are decompositions:

41 + 8655527 = 8655568
71 + 8655497 = 8655568
167 + 8655401 = 8655568
197 + 8655371 = 8655568
281 + 8655287 = 8655568
401 + 8655167 = 8655568
419 + 8655149 = 8655568
521 + 8655047 = 8655568

Showing the first eight; more decompositions exist.
