Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498086, here are decompositions:

17 + 31498069 = 31498086
43 + 31498043 = 31498086
47 + 31498039 = 31498086
79 + 31498007 = 31498086
83 + 31498003 = 31498086
89 + 31497997 = 31498086
107 + 31497979 = 31498086
157 + 31497929 = 31498086

Showing the first eight; more decompositions exist.
