Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450382, here are decompositions:

13 + 31450369 = 31450382
31 + 31450351 = 31450382
163 + 31450219 = 31450382
241 + 31450141 = 31450382
283 + 31450099 = 31450382
349 + 31450033 = 31450382
631 + 31449751 = 31450382
643 + 31449739 = 31450382

Showing the first eight; more decompositions exist.
