Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484098, here are decompositions:

5 + 31484093 = 31484098
17 + 31484081 = 31484098
29 + 31484069 = 31484098
179 + 31483919 = 31484098
227 + 31483871 = 31484098
257 + 31483841 = 31484098
449 + 31483649 = 31484098
521 + 31483577 = 31484098

Showing the first eight; more decompositions exist.
