Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484210, here are decompositions:

3 + 31484207 = 31484210
7 + 31484203 = 31484210
31 + 31484179 = 31484210
67 + 31484143 = 31484210
139 + 31484071 = 31484210
151 + 31484059 = 31484210
229 + 31483981 = 31484210
283 + 31483927 = 31484210

Showing the first eight; more decompositions exist.
