Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484004, here are decompositions:

23 + 31483981 = 31484004
47 + 31483957 = 31484004
127 + 31483877 = 31484004
163 + 31483841 = 31484004
197 + 31483807 = 31484004
271 + 31483733 = 31484004
281 + 31483723 = 31484004
313 + 31483691 = 31484004

Showing the first eight; more decompositions exist.
