Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045658, here are decompositions:

7 + 1045651 = 1045658
37 + 1045621 = 1045658
109 + 1045549 = 1045658
151 + 1045507 = 1045658
337 + 1045321 = 1045658
349 + 1045309 = 1045658
421 + 1045237 = 1045658
541 + 1045117 = 1045658

Showing the first eight; more decompositions exist.
