Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011388, here are decompositions:

11 + 1011377 = 1011388
17 + 1011371 = 1011388
29 + 1011359 = 1011388
107 + 1011281 = 1011388
149 + 1011239 = 1011388
167 + 1011221 = 1011388
197 + 1011191 = 1011388
251 + 1011137 = 1011388

Showing the first eight; more decompositions exist.
