Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484130, here are decompositions:

37 + 31484093 = 31484130
59 + 31484071 = 31484130
61 + 31484069 = 31484130
71 + 31484059 = 31484130
149 + 31483981 = 31484130
151 + 31483979 = 31484130
173 + 31483957 = 31484130
211 + 31483919 = 31484130

Showing the first eight; more decompositions exist.
