Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701228, here are decompositions:

17 + 8701211 = 8701228
227 + 8701001 = 8701228
281 + 8700947 = 8701228
317 + 8700911 = 8701228
359 + 8700869 = 8701228
401 + 8700827 = 8701228
461 + 8700767 = 8701228
647 + 8700581 = 8701228

Showing the first eight; more decompositions exist.
