Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484914, here are decompositions:

3 + 31484911 = 31484914
11 + 31484903 = 31484914
113 + 31484801 = 31484914
137 + 31484777 = 31484914
173 + 31484741 = 31484914
401 + 31484513 = 31484914
647 + 31484267 = 31484914
677 + 31484237 = 31484914

Showing the first eight; more decompositions exist.
