Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655586, here are decompositions:

59 + 8655527 = 8655586
89 + 8655497 = 8655586
389 + 8655197 = 8655586
419 + 8655167 = 8655586
557 + 8655029 = 8655586
827 + 8654759 = 8655586
857 + 8654729 = 8655586
977 + 8654609 = 8655586

Showing the first eight; more decompositions exist.
