Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648658, here are decompositions:

101 + 8648557 = 8648658
107 + 8648551 = 8648658
127 + 8648531 = 8648658
157 + 8648501 = 8648658
199 + 8648459 = 8648658
211 + 8648447 = 8648658
269 + 8648389 = 8648658
311 + 8648347 = 8648658

Showing the first eight; more decompositions exist.
