Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1044390, here are decompositions:

7 + 1044383 = 1044390
19 + 1044371 = 1044390
23 + 1044367 = 1044390
37 + 1044353 = 1044390
43 + 1044347 = 1044390
47 + 1044343 = 1044390
101 + 1044289 = 1044390
103 + 1044287 = 1044390

Showing the first eight; more decompositions exist.
