Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999580, here are decompositions:

17 + 999563 = 999580
59 + 999521 = 999580
89 + 999491 = 999580
149 + 999431 = 999580
191 + 999389 = 999580
251 + 999329 = 999580
293 + 999287 = 999580
311 + 999269 = 999580

Showing the first eight; more decompositions exist.
