Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474382, here are decompositions:

19 + 31474363 = 31474382
31 + 31474351 = 31474382
211 + 31474171 = 31474382
241 + 31474141 = 31474382
271 + 31474111 = 31474382
349 + 31474033 = 31474382
571 + 31473811 = 31474382
601 + 31473781 = 31474382

Showing the first eight; more decompositions exist.
