Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584088, here are decompositions:

89 + 31583999 = 31584088
167 + 31583921 = 31584088
191 + 31583897 = 31584088
251 + 31583837 = 31584088
257 + 31583831 = 31584088
269 + 31583819 = 31584088
311 + 31583777 = 31584088
317 + 31583771 = 31584088

Showing the first eight; more decompositions exist.
