Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628226, here are decompositions:

23 + 8628203 = 8628226
53 + 8628173 = 8628226
149 + 8628077 = 8628226
239 + 8627987 = 8628226
317 + 8627909 = 8628226
359 + 8627867 = 8628226
419 + 8627807 = 8628226
449 + 8627777 = 8628226

Showing the first eight; more decompositions exist.
