Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484818, here are decompositions:

17 + 31484801 = 31484818
41 + 31484777 = 31484818
47 + 31484771 = 31484818
107 + 31484711 = 31484818
191 + 31484627 = 31484818
401 + 31484417 = 31484818
479 + 31484339 = 31484818
641 + 31484177 = 31484818

Showing the first eight; more decompositions exist.
