Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038618, here are decompositions:

17 + 1038601 = 1038618
19 + 1038599 = 1038618
29 + 1038589 = 1038618
79 + 1038539 = 1038618
89 + 1038529 = 1038618
131 + 1038487 = 1038618
197 + 1038421 = 1038618
227 + 1038391 = 1038618

Showing the first eight; more decompositions exist.
