Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993490, here are decompositions:

11 + 993479 = 993490
23 + 993467 = 993490
53 + 993437 = 993490
59 + 993431 = 993490
83 + 993407 = 993490
89 + 993401 = 993490
149 + 993341 = 993490
167 + 993323 = 993490

Showing the first eight; more decompositions exist.
