Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011428, here are decompositions:

31 + 1011397 = 1011428
37 + 1011391 = 1011428
79 + 1011349 = 1011428
97 + 1011331 = 1011428
139 + 1011289 = 1011428
151 + 1011277 = 1011428
157 + 1011271 = 1011428
199 + 1011229 = 1011428

Showing the first eight; more decompositions exist.
