Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498976, here are decompositions:

13 + 31498963 = 31498976
79 + 31498897 = 31498976
97 + 31498879 = 31498976
109 + 31498867 = 31498976
127 + 31498849 = 31498976
139 + 31498837 = 31498976
163 + 31498813 = 31498976
337 + 31498639 = 31498976

Showing the first eight; more decompositions exist.
