Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484342, here are decompositions:

3 + 31484339 = 31484342
61 + 31484281 = 31484342
103 + 31484239 = 31484342
139 + 31484203 = 31484342
163 + 31484179 = 31484342
181 + 31484161 = 31484342
199 + 31484143 = 31484342
271 + 31484071 = 31484342

Showing the first eight; more decompositions exist.
