Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993988, here are decompositions:

5 + 993983 = 993988
11 + 993977 = 993988
101 + 993887 = 993988
137 + 993851 = 993988
167 + 993821 = 993988
431 + 993557 = 993988
461 + 993527 = 993988
509 + 993479 = 993988

Showing the first eight; more decompositions exist.
