Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484862, here are decompositions:

23 + 31484839 = 31484862
41 + 31484821 = 31484862
61 + 31484801 = 31484862
109 + 31484753 = 31484862
151 + 31484711 = 31484862
163 + 31484699 = 31484862
293 + 31484569 = 31484862
349 + 31484513 = 31484862

Showing the first eight; more decompositions exist.
