Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482472, here are decompositions:

71 + 31482401 = 31482472
83 + 31482389 = 31482472
179 + 31482293 = 31482472
191 + 31482281 = 31482472
293 + 31482179 = 31482472
353 + 31482119 = 31482472
383 + 31482089 = 31482472
389 + 31482083 = 31482472

Showing the first eight; more decompositions exist.
