Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648490, here are decompositions:

31 + 8648459 = 8648490
43 + 8648447 = 8648490
101 + 8648389 = 8648490
157 + 8648333 = 8648490
167 + 8648323 = 8648490
173 + 8648317 = 8648490
223 + 8648267 = 8648490
239 + 8648251 = 8648490

Showing the first eight; more decompositions exist.
