Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051558, here are decompositions:

5 + 1051553 = 1051558
59 + 1051499 = 1051558
89 + 1051469 = 1051558
149 + 1051409 = 1051558
239 + 1051319 = 1051558
257 + 1051301 = 1051558
281 + 1051277 = 1051558
311 + 1051247 = 1051558

Showing the first eight; more decompositions exist.
