Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018930, here are decompositions:

23 + 1018907 = 1018930
41 + 1018889 = 1018930
71 + 1018859 = 1018930
113 + 1018817 = 1018930
167 + 1018763 = 1018930
197 + 1018733 = 1018930
233 + 1018697 = 1018930
251 + 1018679 = 1018930

Showing the first eight; more decompositions exist.
