Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584118, here are decompositions:

17 + 31584101 = 31584118
197 + 31583921 = 31584118
281 + 31583837 = 31584118
347 + 31583771 = 31584118
389 + 31583729 = 31584118
431 + 31583687 = 31584118
491 + 31583627 = 31584118
521 + 31583597 = 31584118

Showing the first eight; more decompositions exist.
