Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532446, here are decompositions:

17 + 31532429 = 31532446
107 + 31532339 = 31532446
167 + 31532279 = 31532446
227 + 31532219 = 31532446
383 + 31532063 = 31532446
443 + 31532003 = 31532446
479 + 31531967 = 31532446
563 + 31531883 = 31532446

Showing the first eight; more decompositions exist.
