Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993538, here are decompositions:

11 + 993527 = 993538
59 + 993479 = 993538
71 + 993467 = 993538
101 + 993437 = 993538
107 + 993431 = 993538
131 + 993407 = 993538
137 + 993401 = 993538
197 + 993341 = 993538

Showing the first eight; more decompositions exist.
