Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474904, here are decompositions:

31 + 31474873 = 31474904
37 + 31474867 = 31474904
103 + 31474801 = 31474904
127 + 31474777 = 31474904
157 + 31474747 = 31474904
211 + 31474693 = 31474904
541 + 31474363 = 31474904
547 + 31474357 = 31474904

Showing the first eight; more decompositions exist.
