Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484282, here are decompositions:

43 + 31484239 = 31484282
73 + 31484209 = 31484282
79 + 31484203 = 31484282
103 + 31484179 = 31484282
139 + 31484143 = 31484282
211 + 31484071 = 31484282
223 + 31484059 = 31484282
421 + 31483861 = 31484282

Showing the first eight; more decompositions exist.
