Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018894, here are decompositions:

5 + 1018889 = 1018894
83 + 1018811 = 1018894
131 + 1018763 = 1018894
197 + 1018697 = 1018894
251 + 1018643 = 1018894
281 + 1018613 = 1018894
311 + 1018583 = 1018894
557 + 1018337 = 1018894

Showing the first eight; more decompositions exist.
