Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496008, here are decompositions:

29 + 31495979 = 31496008
59 + 31495949 = 31496008
149 + 31495859 = 31496008
251 + 31495757 = 31496008
317 + 31495691 = 31496008
347 + 31495661 = 31496008
419 + 31495589 = 31496008
491 + 31495517 = 31496008

Showing the first eight; more decompositions exist.
