Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655200, here are decompositions:

3 + 8655197 = 8655200
97 + 8655103 = 8655200
163 + 8655037 = 8655200
193 + 8655007 = 8655200
241 + 8654959 = 8655200
283 + 8654917 = 8655200
397 + 8654803 = 8655200
439 + 8654761 = 8655200

Showing the first eight; more decompositions exist.
