Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655806, here are decompositions:

37 + 8655769 = 8655806
67 + 8655739 = 8655806
73 + 8655733 = 8655806
127 + 8655679 = 8655806
157 + 8655649 = 8655806
349 + 8655457 = 8655806
373 + 8655433 = 8655806
457 + 8655349 = 8655806

Showing the first eight; more decompositions exist.
