Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568466, here are decompositions:

43 + 31568423 = 31568466
47 + 31568419 = 31568466
53 + 31568413 = 31568466
67 + 31568399 = 31568466
73 + 31568393 = 31568466
79 + 31568387 = 31568466
109 + 31568357 = 31568466
113 + 31568353 = 31568466

Showing the first eight; more decompositions exist.
