Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568446, here are decompositions:

23 + 31568423 = 31568446
29 + 31568417 = 31568446
47 + 31568399 = 31568446
53 + 31568393 = 31568446
59 + 31568387 = 31568446
89 + 31568357 = 31568446
113 + 31568333 = 31568446
137 + 31568309 = 31568446

Showing the first eight; more decompositions exist.
