Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584070, here are decompositions:

3 + 31584067 = 31584070
71 + 31583999 = 31584070
149 + 31583921 = 31584070
173 + 31583897 = 31584070
233 + 31583837 = 31584070
239 + 31583831 = 31584070
251 + 31583819 = 31584070
293 + 31583777 = 31584070

Showing the first eight; more decompositions exist.
