Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482722, here are decompositions:

13 + 31482709 = 31482722
79 + 31482643 = 31482722
109 + 31482613 = 31482722
163 + 31482559 = 31482722
211 + 31482511 = 31482722
223 + 31482499 = 31482722
283 + 31482439 = 31482722
373 + 31482349 = 31482722

Showing the first eight; more decompositions exist.
