Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474562, here are decompositions:

3 + 31474559 = 31474562
13 + 31474549 = 31474562
43 + 31474519 = 31474562
61 + 31474501 = 31474562
73 + 31474489 = 31474562
139 + 31474423 = 31474562
199 + 31474363 = 31474562
211 + 31474351 = 31474562

Showing the first eight; more decompositions exist.
