Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018946, here are decompositions:

43 + 1018903 = 1018946
67 + 1018879 = 1018946
73 + 1018873 = 1018946
139 + 1018807 = 1018946
157 + 1018789 = 1018946
277 + 1018669 = 1018946
433 + 1018513 = 1018946
457 + 1018489 = 1018946

Showing the first eight; more decompositions exist.
