Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582274, here are decompositions:

7 + 31582267 = 31582274
67 + 31582207 = 31582274
103 + 31582171 = 31582274
181 + 31582093 = 31582274
271 + 31582003 = 31582274
277 + 31581997 = 31582274
313 + 31581961 = 31582274
397 + 31581877 = 31582274

Showing the first eight; more decompositions exist.
