Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584752, here are decompositions:

139 + 31584613 = 31584752
151 + 31584601 = 31584752
193 + 31584559 = 31584752
211 + 31584541 = 31584752
229 + 31584523 = 31584752
271 + 31584481 = 31584752
313 + 31584439 = 31584752
379 + 31584373 = 31584752

Showing the first eight; more decompositions exist.
