Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584466, here are decompositions:

59 + 31584407 = 31584466
83 + 31584383 = 31584466
167 + 31584299 = 31584466
233 + 31584233 = 31584466
269 + 31584197 = 31584466
293 + 31584173 = 31584466
467 + 31583999 = 31584466
569 + 31583897 = 31584466

Showing the first eight; more decompositions exist.
