Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484220, here are decompositions:

11 + 31484209 = 31484220
13 + 31484207 = 31484220
17 + 31484203 = 31484220
41 + 31484179 = 31484220
43 + 31484177 = 31484220
59 + 31484161 = 31484220
127 + 31484093 = 31484220
139 + 31484081 = 31484220

Showing the first eight; more decompositions exist.
