Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018226, here are decompositions:

3 + 1018223 = 1018226
19 + 1018207 = 1018226
103 + 1018123 = 1018226
229 + 1017997 = 1018226
337 + 1017889 = 1018226
367 + 1017859 = 1018226
379 + 1017847 = 1018226
409 + 1017817 = 1018226

Showing the first eight; more decompositions exist.
