Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045928, here are decompositions:

109 + 1045819 = 1045928
127 + 1045801 = 1045928
199 + 1045729 = 1045928
277 + 1045651 = 1045928
307 + 1045621 = 1045928
379 + 1045549 = 1045928
421 + 1045507 = 1045928
607 + 1045321 = 1045928

Showing the first eight; more decompositions exist.
