Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582316, here are decompositions:

67 + 31582249 = 31582316
109 + 31582207 = 31582316
223 + 31582093 = 31582316
313 + 31582003 = 31582316
433 + 31581883 = 31582316
439 + 31581877 = 31582316
457 + 31581859 = 31582316
499 + 31581817 = 31582316

Showing the first eight; more decompositions exist.
