Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993442, here are decompositions:

5 + 993437 = 993442
11 + 993431 = 993442
41 + 993401 = 993442
101 + 993341 = 993442
173 + 993269 = 993442
239 + 993203 = 993442
389 + 993053 = 993442
431 + 993011 = 993442

Showing the first eight; more decompositions exist.
