Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31517696, here are decompositions:

43 + 31517653 = 31517696
79 + 31517617 = 31517696
109 + 31517587 = 31517696
139 + 31517557 = 31517696
163 + 31517533 = 31517696
229 + 31517467 = 31517696
283 + 31517413 = 31517696
307 + 31517389 = 31517696

Showing the first eight; more decompositions exist.
