Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999574, here are decompositions:

11 + 999563 = 999574
53 + 999521 = 999574
83 + 999491 = 999574
137 + 999437 = 999574
197 + 999377 = 999574
353 + 999221 = 999574
491 + 999083 = 999574
617 + 998957 = 999574

Showing the first eight; more decompositions exist.
