Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484000, here are decompositions:

19 + 31483981 = 31484000
43 + 31483957 = 31484000
73 + 31483927 = 31484000
139 + 31483861 = 31484000
181 + 31483819 = 31484000
193 + 31483807 = 31484000
199 + 31483801 = 31484000
211 + 31483789 = 31484000

Showing the first eight; more decompositions exist.
