Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648538, here are decompositions:

5 + 8648533 = 8648538
7 + 8648531 = 8648538
37 + 8648501 = 8648538
79 + 8648459 = 8648538
149 + 8648389 = 8648538
167 + 8648371 = 8648538
191 + 8648347 = 8648538
271 + 8648267 = 8648538

Showing the first eight; more decompositions exist.
