Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018644, here are decompositions:

23 + 1018621 = 1018644
31 + 1018613 = 1018644
61 + 1018583 = 1018644
101 + 1018543 = 1018644
131 + 1018513 = 1018644
167 + 1018477 = 1018644
173 + 1018471 = 1018644
197 + 1018447 = 1018644

Showing the first eight; more decompositions exist.
