Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484208, here are decompositions:

5 + 31484203 = 31484208
29 + 31484179 = 31484208
31 + 31484177 = 31484208
47 + 31484161 = 31484208
79 + 31484129 = 31484208
127 + 31484081 = 31484208
137 + 31484071 = 31484208
139 + 31484069 = 31484208

Showing the first eight; more decompositions exist.
