Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051438, here are decompositions:

29 + 1051409 = 1051438
41 + 1051397 = 1051438
137 + 1051301 = 1051438
191 + 1051247 = 1051438
257 + 1051181 = 1051438
281 + 1051157 = 1051438
359 + 1051079 = 1051438
419 + 1051019 = 1051438

Showing the first eight; more decompositions exist.
