Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568622, here are decompositions:

11 + 31568611 = 31568622
61 + 31568561 = 31568622
79 + 31568543 = 31568622
83 + 31568539 = 31568622
131 + 31568491 = 31568622
199 + 31568423 = 31568622
223 + 31568399 = 31568622
229 + 31568393 = 31568622

Showing the first eight; more decompositions exist.
