Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051822, here are decompositions:

3 + 1051819 = 1051822
11 + 1051811 = 1051822
41 + 1051781 = 1051822
59 + 1051763 = 1051822
113 + 1051709 = 1051822
173 + 1051649 = 1051822
179 + 1051643 = 1051822
251 + 1051571 = 1051822

Showing the first eight; more decompositions exist.
