Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621292, here are decompositions:

11 + 8621281 = 8621292
79 + 8621213 = 8621292
83 + 8621209 = 8621292
103 + 8621189 = 8621292
109 + 8621183 = 8621292
139 + 8621153 = 8621292
149 + 8621143 = 8621292
191 + 8621101 = 8621292

Showing the first eight; more decompositions exist.
