Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051386, here are decompositions:

13 + 1051373 = 1051386
53 + 1051333 = 1051386
67 + 1051319 = 1051386
73 + 1051313 = 1051386
103 + 1051283 = 1051386
109 + 1051277 = 1051386
139 + 1051247 = 1051386
229 + 1051157 = 1051386

Showing the first eight; more decompositions exist.
