Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484982, here are decompositions:

41 + 31484941 = 31484982
71 + 31484911 = 31484982
79 + 31484903 = 31484982
181 + 31484801 = 31484982
211 + 31484771 = 31484982
229 + 31484753 = 31484982
241 + 31484741 = 31484982
271 + 31484711 = 31484982

Showing the first eight; more decompositions exist.
