Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484082, here are decompositions:

11 + 31484071 = 31484082
13 + 31484069 = 31484082
23 + 31484059 = 31484082
101 + 31483981 = 31484082
103 + 31483979 = 31484082
163 + 31483919 = 31484082
193 + 31483889 = 31484082
199 + 31483883 = 31484082

Showing the first eight; more decompositions exist.
