Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474808, here are decompositions:

7 + 31474801 = 31474808
31 + 31474777 = 31474808
61 + 31474747 = 31474808
139 + 31474669 = 31474808
307 + 31474501 = 31474808
457 + 31474351 = 31474808
751 + 31474057 = 31474808
877 + 31473931 = 31474808

Showing the first eight; more decompositions exist.
