Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484008, here are decompositions:

29 + 31483979 = 31484008
89 + 31483919 = 31484008
131 + 31483877 = 31484008
137 + 31483871 = 31484008
167 + 31483841 = 31484008
317 + 31483691 = 31484008
359 + 31483649 = 31484008
431 + 31483577 = 31484008

Showing the first eight; more decompositions exist.
