Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013228, here are decompositions:

31 + 1013197 = 1013228
199 + 1013029 = 1013228
367 + 1012861 = 1013228
397 + 1012831 = 1013228
439 + 1012789 = 1013228
457 + 1012771 = 1013228
571 + 1012657 = 1013228
631 + 1012597 = 1013228

Showing the first eight; more decompositions exist.
