Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496040, here are decompositions:

13 + 31496027 = 31496040
29 + 31496011 = 31496040
61 + 31495979 = 31496040
181 + 31495859 = 31496040
193 + 31495847 = 31496040
239 + 31495801 = 31496040
283 + 31495757 = 31496040
307 + 31495733 = 31496040

Showing the first eight; more decompositions exist.
