Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498836, here are decompositions:

7 + 31498829 = 31498836
23 + 31498813 = 31498836
73 + 31498763 = 31498836
179 + 31498657 = 31498836
197 + 31498639 = 31498836
277 + 31498559 = 31498836
307 + 31498529 = 31498836
337 + 31498499 = 31498836

Showing the first eight; more decompositions exist.
