Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498030, here are decompositions:

23 + 31498007 = 31498030
89 + 31497941 = 31498030
101 + 31497929 = 31498030
167 + 31497863 = 31498030
227 + 31497803 = 31498030
233 + 31497797 = 31498030
257 + 31497773 = 31498030
293 + 31497737 = 31498030

Showing the first eight; more decompositions exist.
