Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051290, here are decompositions:

7 + 1051283 = 1051290
13 + 1051277 = 1051290
43 + 1051247 = 1051290
109 + 1051181 = 1051290
113 + 1051177 = 1051290
137 + 1051153 = 1051290
139 + 1051151 = 1051290
151 + 1051139 = 1051290

Showing the first eight; more decompositions exist.
