Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011278, here are decompositions:

7 + 1011271 = 1011278
61 + 1011217 = 1011278
139 + 1011139 = 1011278
199 + 1011079 = 1011278
211 + 1011067 = 1011278
241 + 1011037 = 1011278
277 + 1011001 = 1011278
349 + 1010929 = 1011278

Showing the first eight; more decompositions exist.
