Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051586, here are decompositions:

37 + 1051549 = 1051586
43 + 1051543 = 1051586
79 + 1051507 = 1051586
127 + 1051459 = 1051586
163 + 1051423 = 1051586
409 + 1051177 = 1051586
433 + 1051153 = 1051586
439 + 1051147 = 1051586

Showing the first eight; more decompositions exist.
