Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582752, here are decompositions:

13 + 31582739 = 31582752
23 + 31582729 = 31582752
73 + 31582679 = 31582752
79 + 31582673 = 31582752
139 + 31582613 = 31582752
151 + 31582601 = 31582752
163 + 31582589 = 31582752
193 + 31582559 = 31582752

Showing the first eight; more decompositions exist.
