Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484108, here are decompositions:

37 + 31484071 = 31484108
127 + 31483981 = 31484108
151 + 31483957 = 31484108
181 + 31483927 = 31484108
307 + 31483801 = 31484108
349 + 31483759 = 31484108
661 + 31483447 = 31484108
739 + 31483369 = 31484108

Showing the first eight; more decompositions exist.
