Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999622, here are decompositions:

11 + 999611 = 999622
23 + 999599 = 999622
59 + 999563 = 999622
101 + 999521 = 999622
131 + 999491 = 999622
191 + 999431 = 999622
233 + 999389 = 999622
251 + 999371 = 999622

Showing the first eight; more decompositions exist.
