Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484908, here are decompositions:

5 + 31484903 = 31484908
71 + 31484837 = 31484908
107 + 31484801 = 31484908
131 + 31484777 = 31484908
137 + 31484771 = 31484908
167 + 31484741 = 31484908
197 + 31484711 = 31484908
281 + 31484627 = 31484908

Showing the first eight; more decompositions exist.
