Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498916, here are decompositions:

3 + 31498913 = 31498916
19 + 31498897 = 31498916
37 + 31498879 = 31498916
67 + 31498849 = 31498916
79 + 31498837 = 31498916
103 + 31498813 = 31498916
277 + 31498639 = 31498916
367 + 31498549 = 31498916

Showing the first eight; more decompositions exist.
