Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051840, here are decompositions:

11 + 1051829 = 1051840
29 + 1051811 = 1051840
59 + 1051781 = 1051840
131 + 1051709 = 1051840
191 + 1051649 = 1051840
197 + 1051643 = 1051840
233 + 1051607 = 1051840
239 + 1051601 = 1051840

Showing the first eight; more decompositions exist.
