Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568836, here are decompositions:

3 + 31568833 = 31568836
113 + 31568723 = 31568836
179 + 31568657 = 31568836
293 + 31568543 = 31568836
419 + 31568417 = 31568836
443 + 31568393 = 31568836
449 + 31568387 = 31568836
479 + 31568357 = 31568836

Showing the first eight; more decompositions exist.
