Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483708, here are decompositions:

17 + 31483691 = 31483708
59 + 31483649 = 31483708
131 + 31483577 = 31483708
239 + 31483469 = 31483708
251 + 31483457 = 31483708
317 + 31483391 = 31483708
401 + 31483307 = 31483708
479 + 31483229 = 31483708

Showing the first eight; more decompositions exist.
