Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582614, here are decompositions:

5 + 31582609 = 31582614
13 + 31582601 = 31582614
61 + 31582553 = 31582614
67 + 31582547 = 31582614
83 + 31582531 = 31582614
101 + 31582513 = 31582614
197 + 31582417 = 31582614
211 + 31582403 = 31582614

Showing the first eight; more decompositions exist.
