Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584434, here are decompositions:

3 + 31584431 = 31584434
61 + 31584373 = 31584434
73 + 31584361 = 31584434
97 + 31584337 = 31584434
127 + 31584307 = 31584434
223 + 31584211 = 31584434
241 + 31584193 = 31584434
367 + 31584067 = 31584434

Showing the first eight; more decompositions exist.
