Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582684, here are decompositions:

5 + 31582679 = 31582684
11 + 31582673 = 31582684
17 + 31582667 = 31582684
53 + 31582631 = 31582684
71 + 31582613 = 31582684
83 + 31582601 = 31582684
131 + 31582553 = 31582684
137 + 31582547 = 31582684

Showing the first eight; more decompositions exist.
