Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474706, here are decompositions:

13 + 31474693 = 31474706
19 + 31474687 = 31474706
37 + 31474669 = 31474706
157 + 31474549 = 31474706
283 + 31474423 = 31474706
349 + 31474357 = 31474706
457 + 31474249 = 31474706
577 + 31474129 = 31474706

Showing the first eight; more decompositions exist.
