Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498098, here are decompositions:

11 + 31498087 = 31498098
29 + 31498069 = 31498098
59 + 31498039 = 31498098
89 + 31498009 = 31498098
101 + 31497997 = 31498098
157 + 31497941 = 31498098
167 + 31497931 = 31498098
227 + 31497871 = 31498098

Showing the first eight; more decompositions exist.
