Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522432, here are decompositions:

59 + 31522373 = 31522432
101 + 31522331 = 31522432
191 + 31522241 = 31522432
251 + 31522181 = 31522432
419 + 31522013 = 31522432
479 + 31521953 = 31522432
569 + 31521863 = 31522432
719 + 31521713 = 31522432

Showing the first eight; more decompositions exist.
