Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051618, here are decompositions:

11 + 1051607 = 1051618
17 + 1051601 = 1051618
47 + 1051571 = 1051618
59 + 1051559 = 1051618
137 + 1051481 = 1051618
149 + 1051469 = 1051618
317 + 1051301 = 1051618
461 + 1051157 = 1051618

Showing the first eight; more decompositions exist.
