Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988028, here are decompositions:

7 + 988021 = 988028
31 + 987997 = 988028
37 + 987991 = 988028
331 + 987697 = 988028
397 + 987631 = 988028
421 + 987607 = 988028
487 + 987541 = 988028
571 + 987457 = 988028

Showing the first eight; more decompositions exist.
