Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993478, here are decompositions:

11 + 993467 = 993478
41 + 993437 = 993478
47 + 993431 = 993478
71 + 993407 = 993478
137 + 993341 = 993478
191 + 993287 = 993478
281 + 993197 = 993478
467 + 993011 = 993478

Showing the first eight; more decompositions exist.
