Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626208, here are decompositions:

67 + 8626141 = 8626208
79 + 8626129 = 8626208
109 + 8626099 = 8626208
211 + 8625997 = 8626208
229 + 8625979 = 8626208
307 + 8625901 = 8626208
397 + 8625811 = 8626208
421 + 8625787 = 8626208

Showing the first eight; more decompositions exist.
