Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993550, here are decompositions:

23 + 993527 = 993550
71 + 993479 = 993550
83 + 993467 = 993550
113 + 993437 = 993550
149 + 993401 = 993550
227 + 993323 = 993550
263 + 993287 = 993550
281 + 993269 = 993550

Showing the first eight; more decompositions exist.
