Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498944, here are decompositions:

13 + 31498931 = 31498944
31 + 31498913 = 31498944
47 + 31498897 = 31498944
97 + 31498847 = 31498944
107 + 31498837 = 31498944
131 + 31498813 = 31498944
181 + 31498763 = 31498944
241 + 31498703 = 31498944

Showing the first eight; more decompositions exist.
