Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484838, here are decompositions:

17 + 31484821 = 31484838
37 + 31484801 = 31484838
41 + 31484797 = 31484838
61 + 31484777 = 31484838
67 + 31484771 = 31484838
97 + 31484741 = 31484838
127 + 31484711 = 31484838
139 + 31484699 = 31484838

Showing the first eight; more decompositions exist.
