Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484944, here are decompositions:

3 + 31484941 = 31484944
41 + 31484903 = 31484944
107 + 31484837 = 31484944
167 + 31484777 = 31484944
173 + 31484771 = 31484944
191 + 31484753 = 31484944
233 + 31484711 = 31484944
317 + 31484627 = 31484944

Showing the first eight; more decompositions exist.
