Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474376, here are decompositions:

13 + 31474363 = 31474376
19 + 31474357 = 31474376
127 + 31474249 = 31474376
163 + 31474213 = 31474376
643 + 31473733 = 31474376
673 + 31473703 = 31474376
853 + 31473523 = 31474376
919 + 31473457 = 31474376

Showing the first eight; more decompositions exist.
