Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474892, here are decompositions:

19 + 31474873 = 31474892
109 + 31474783 = 31474892
199 + 31474693 = 31474892
223 + 31474669 = 31474892
373 + 31474519 = 31474892
541 + 31474351 = 31474892
601 + 31474291 = 31474892
643 + 31474249 = 31474892

Showing the first eight; more decompositions exist.
