Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584632, here are decompositions:

19 + 31584613 = 31584632
31 + 31584601 = 31584632
73 + 31584559 = 31584632
109 + 31584523 = 31584632
151 + 31584481 = 31584632
193 + 31584439 = 31584632
271 + 31584361 = 31584632
421 + 31584211 = 31584632

Showing the first eight; more decompositions exist.
