Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042946, here are decompositions:

43 + 1042903 = 1042946
97 + 1042849 = 1042946
109 + 1042837 = 1042946
127 + 1042819 = 1042946
313 + 1042633 = 1042946
337 + 1042609 = 1042946
349 + 1042597 = 1042946
547 + 1042399 = 1042946

Showing the first eight; more decompositions exist.
