Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482342, here are decompositions:

5 + 31482337 = 31482342
61 + 31482281 = 31482342
71 + 31482271 = 31482342
113 + 31482229 = 31482342
163 + 31482179 = 31482342
173 + 31482169 = 31482342
223 + 31482119 = 31482342
239 + 31482103 = 31482342

Showing the first eight; more decompositions exist.
