Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582232, here are decompositions:

61 + 31582171 = 31582232
139 + 31582093 = 31582232
211 + 31582021 = 31582232
229 + 31582003 = 31582232
271 + 31581961 = 31582232
349 + 31581883 = 31582232
373 + 31581859 = 31582232
439 + 31581793 = 31582232

Showing the first eight; more decompositions exist.
