Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011238, here are decompositions:

5 + 1011233 = 1011238
17 + 1011221 = 1011238
47 + 1011191 = 1011238
71 + 1011167 = 1011238
101 + 1011137 = 1011238
131 + 1011107 = 1011238
167 + 1011071 = 1011238
257 + 1010981 = 1011238

Showing the first eight; more decompositions exist.
