Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474844, here are decompositions:

43 + 31474801 = 31474844
61 + 31474783 = 31474844
67 + 31474777 = 31474844
97 + 31474747 = 31474844
151 + 31474693 = 31474844
157 + 31474687 = 31474844
421 + 31474423 = 31474844
487 + 31474357 = 31474844

Showing the first eight; more decompositions exist.
