Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584504, here are decompositions:

5 + 31584499 = 31584504
23 + 31584481 = 31584504
47 + 31584457 = 31584504
73 + 31584431 = 31584504
97 + 31584407 = 31584504
103 + 31584401 = 31584504
131 + 31584373 = 31584504
167 + 31584337 = 31584504

Showing the first eight; more decompositions exist.
