Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568084, here are decompositions:

13 + 31568071 = 31568084
43 + 31568041 = 31568084
103 + 31567981 = 31568084
271 + 31567813 = 31568084
367 + 31567717 = 31568084
397 + 31567687 = 31568084
463 + 31567621 = 31568084
571 + 31567513 = 31568084

Showing the first eight; more decompositions exist.
