Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484232, here are decompositions:

23 + 31484209 = 31484232
29 + 31484203 = 31484232
53 + 31484179 = 31484232
71 + 31484161 = 31484232
89 + 31484143 = 31484232
103 + 31484129 = 31484232
139 + 31484093 = 31484232
151 + 31484081 = 31484232

Showing the first eight; more decompositions exist.
