Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484030, here are decompositions:

73 + 31483957 = 31484030
103 + 31483927 = 31484030
211 + 31483819 = 31484030
223 + 31483807 = 31484030
229 + 31483801 = 31484030
241 + 31483789 = 31484030
271 + 31483759 = 31484030
307 + 31483723 = 31484030

Showing the first eight; more decompositions exist.
