Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568066, here are decompositions:

7 + 31568059 = 31568066
67 + 31567999 = 31568066
337 + 31567729 = 31568066
349 + 31567717 = 31568066
367 + 31567699 = 31568066
373 + 31567693 = 31568066
379 + 31567687 = 31568066
463 + 31567603 = 31568066

Showing the first eight; more decompositions exist.
