Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474712, here are decompositions:

19 + 31474693 = 31474712
43 + 31474669 = 31474712
163 + 31474549 = 31474712
193 + 31474519 = 31474712
211 + 31474501 = 31474712
223 + 31474489 = 31474712
349 + 31474363 = 31474712
421 + 31474291 = 31474712

Showing the first eight; more decompositions exist.
