Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988928, here are decompositions:

19 + 988909 = 988928
67 + 988861 = 988928
79 + 988849 = 988928
139 + 988789 = 988928
277 + 988651 = 988928
337 + 988591 = 988928
349 + 988579 = 988928
379 + 988549 = 988928

Showing the first eight; more decompositions exist.
