Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484090, here are decompositions:

19 + 31484071 = 31484090
31 + 31484059 = 31484090
109 + 31483981 = 31484090
163 + 31483927 = 31484090
229 + 31483861 = 31484090
271 + 31483819 = 31484090
283 + 31483807 = 31484090
331 + 31483759 = 31484090

Showing the first eight; more decompositions exist.
