Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582708, here are decompositions:

29 + 31582679 = 31582708
41 + 31582667 = 31582708
107 + 31582601 = 31582708
149 + 31582559 = 31582708
389 + 31582319 = 31582708
467 + 31582241 = 31582708
491 + 31582217 = 31582708
587 + 31582121 = 31582708

Showing the first eight; more decompositions exist.
