Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584106, here are decompositions:

5 + 31584101 = 31584106
107 + 31583999 = 31584106
269 + 31583837 = 31584106
353 + 31583753 = 31584106
419 + 31583687 = 31584106
443 + 31583663 = 31584106
479 + 31583627 = 31584106
509 + 31583597 = 31584106

Showing the first eight; more decompositions exist.
