Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589384, here are decompositions:

7 + 31589377 = 31589384
31 + 31589353 = 31589384
67 + 31589317 = 31589384
97 + 31589287 = 31589384
367 + 31589017 = 31589384
373 + 31589011 = 31589384
433 + 31588951 = 31589384
457 + 31588927 = 31589384

Showing the first eight; more decompositions exist.
