Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584076, here are decompositions:

179 + 31583897 = 31584076
239 + 31583837 = 31584076
257 + 31583819 = 31584076
347 + 31583729 = 31584076
383 + 31583693 = 31584076
389 + 31583687 = 31584076
443 + 31583633 = 31584076
449 + 31583627 = 31584076

Showing the first eight; more decompositions exist.
