Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018546, here are decompositions:

3 + 1018543 = 1018546
107 + 1018439 = 1018546
233 + 1018313 = 1018546
293 + 1018253 = 1018546
449 + 1018097 = 1018546
587 + 1017959 = 1018546
593 + 1017953 = 1018546
719 + 1017827 = 1018546

Showing the first eight; more decompositions exist.
