Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999544, here are decompositions:

3 + 999541 = 999544
23 + 999521 = 999544
53 + 999491 = 999544
107 + 999437 = 999544
113 + 999431 = 999544
167 + 999377 = 999544
173 + 999371 = 999544
257 + 999287 = 999544

Showing the first eight; more decompositions exist.
