Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482404, here are decompositions:

3 + 31482401 = 31482404
61 + 31482343 = 31482404
67 + 31482337 = 31482404
97 + 31482307 = 31482404
127 + 31482277 = 31482404
157 + 31482247 = 31482404
307 + 31482097 = 31482404
337 + 31482067 = 31482404

Showing the first eight; more decompositions exist.
