Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655572, here are decompositions:

139 + 8655433 = 8655572
151 + 8655421 = 8655572
223 + 8655349 = 8655572
229 + 8655343 = 8655572
241 + 8655331 = 8655572
313 + 8655259 = 8655572
613 + 8654959 = 8655572
631 + 8654941 = 8655572

Showing the first eight; more decompositions exist.
