Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517484, here are decompositions:

17 + 31517467 = 31517484
43 + 31517441 = 31517484
67 + 31517417 = 31517484
71 + 31517413 = 31517484
73 + 31517411 = 31517484
211 + 31517273 = 31517484
241 + 31517243 = 31517484
277 + 31517207 = 31517484

Showing the first eight; more decompositions exist.
