Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582664, here are decompositions:

31 + 31582633 = 31582664
37 + 31582627 = 31582664
151 + 31582513 = 31582664
193 + 31582471 = 31582664
331 + 31582333 = 31582664
397 + 31582267 = 31582664
457 + 31582207 = 31582664
571 + 31582093 = 31582664

Showing the first eight; more decompositions exist.
