Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584898, here are decompositions:

11 + 31584887 = 31584898
17 + 31584881 = 31584898
29 + 31584869 = 31584898
89 + 31584809 = 31584898
101 + 31584797 = 31584898
281 + 31584617 = 31584898
347 + 31584551 = 31584898
467 + 31584431 = 31584898

Showing the first eight; more decompositions exist.
