Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582136, here are decompositions:

43 + 31582093 = 31582136
109 + 31582027 = 31582136
139 + 31581997 = 31582136
163 + 31581973 = 31582136
277 + 31581859 = 31582136
349 + 31581787 = 31582136
457 + 31581679 = 31582136
463 + 31581673 = 31582136

Showing the first eight; more decompositions exist.
