Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484312, here are decompositions:

31 + 31484281 = 31484312
73 + 31484239 = 31484312
103 + 31484209 = 31484312
109 + 31484203 = 31484312
151 + 31484161 = 31484312
241 + 31484071 = 31484312
331 + 31483981 = 31484312
523 + 31483789 = 31484312

Showing the first eight; more decompositions exist.
