Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018648, here are decompositions:

5 + 1018643 = 1018648
89 + 1018559 = 1018648
227 + 1018421 = 1018648
311 + 1018337 = 1018648
347 + 1018301 = 1018648
401 + 1018247 = 1018648
431 + 1018217 = 1018648
557 + 1018091 = 1018648

Showing the first eight; more decompositions exist.
