Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655842, here are decompositions:

73 + 8655769 = 8655842
103 + 8655739 = 8655842
109 + 8655733 = 8655842
163 + 8655679 = 8655842
193 + 8655649 = 8655842
211 + 8655631 = 8655842
409 + 8655433 = 8655842
421 + 8655421 = 8655842

Showing the first eight; more decompositions exist.
