Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011240, here are decompositions:

7 + 1011233 = 1011240
11 + 1011229 = 1011240
19 + 1011221 = 1011240
23 + 1011217 = 1011240
73 + 1011167 = 1011240
101 + 1011139 = 1011240
103 + 1011137 = 1011240
149 + 1011091 = 1011240

Showing the first eight; more decompositions exist.
