Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482442, here are decompositions:

3 + 31482439 = 31482442
41 + 31482401 = 31482442
53 + 31482389 = 31482442
149 + 31482293 = 31482442
263 + 31482179 = 31482442
269 + 31482173 = 31482442
353 + 31482089 = 31482442
359 + 31482083 = 31482442

Showing the first eight; more decompositions exist.
