Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517734, here are decompositions:

5 + 31517729 = 31517734
11 + 31517723 = 31517734
137 + 31517597 = 31517734
191 + 31517543 = 31517734
233 + 31517501 = 31517734
293 + 31517441 = 31517734
317 + 31517417 = 31517734
461 + 31517273 = 31517734

Showing the first eight; more decompositions exist.
