Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599220, here are decompositions:

61 + 8599159 = 8599220
79 + 8599141 = 8599220
103 + 8599117 = 8599220
109 + 8599111 = 8599220
139 + 8599081 = 8599220
151 + 8599069 = 8599220
193 + 8599027 = 8599220
199 + 8599021 = 8599220

Showing the first eight; more decompositions exist.
