Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648588, here are decompositions:

31 + 8648557 = 8648588
37 + 8648551 = 8648588
199 + 8648389 = 8648588
241 + 8648347 = 8648588
271 + 8648317 = 8648588
337 + 8648251 = 8648588
349 + 8648239 = 8648588
367 + 8648221 = 8648588

Showing the first eight; more decompositions exist.
