Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482372, here are decompositions:

23 + 31482349 = 31482372
29 + 31482343 = 31482372
79 + 31482293 = 31482372
101 + 31482271 = 31482372
193 + 31482179 = 31482372
199 + 31482173 = 31482372
269 + 31482103 = 31482372
283 + 31482089 = 31482372

Showing the first eight; more decompositions exist.
