Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051658, here are decompositions:

19 + 1051639 = 1051658
37 + 1051621 = 1051658
67 + 1051591 = 1051658
109 + 1051549 = 1051658
151 + 1051507 = 1051658
199 + 1051459 = 1051658
241 + 1051417 = 1051658
367 + 1051291 = 1051658

Showing the first eight; more decompositions exist.
