Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568926, here are decompositions:

5 + 31568921 = 31568926
17 + 31568909 = 31568926
29 + 31568897 = 31568926
47 + 31568879 = 31568926
83 + 31568843 = 31568926
269 + 31568657 = 31568926
383 + 31568543 = 31568926
503 + 31568423 = 31568926

Showing the first eight; more decompositions exist.
