Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582202, here are decompositions:

19 + 31582183 = 31582202
31 + 31582171 = 31582202
109 + 31582093 = 31582202
181 + 31582021 = 31582202
199 + 31582003 = 31582202
229 + 31581973 = 31582202
241 + 31581961 = 31582202
313 + 31581889 = 31582202

Showing the first eight; more decompositions exist.
