Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498026, here are decompositions:

17 + 31498009 = 31498026
19 + 31498007 = 31498026
23 + 31498003 = 31498026
29 + 31497997 = 31498026
47 + 31497979 = 31498026
97 + 31497929 = 31498026
163 + 31497863 = 31498026
167 + 31497859 = 31498026

Showing the first eight; more decompositions exist.
