Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582902, here are decompositions:

5 + 31582897 = 31582902
11 + 31582891 = 31582902
79 + 31582823 = 31582902
83 + 31582819 = 31582902
163 + 31582739 = 31582902
173 + 31582729 = 31582902
223 + 31582679 = 31582902
229 + 31582673 = 31582902

Showing the first eight; more decompositions exist.
