Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012838, here are decompositions:

7 + 1012831 = 1012838
67 + 1012771 = 1012838
139 + 1012699 = 1012838
181 + 1012657 = 1012838
241 + 1012597 = 1012838
331 + 1012507 = 1012838
349 + 1012489 = 1012838
439 + 1012399 = 1012838

Showing the first eight; more decompositions exist.
